Download or read book A New Generation of Organic Light Emitting Materials and Devices written by Shi-Jian Su and published by Frontiers Media SA. This book was released on 2019-11-27 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the invention of the first efficient organic light-emitting diodes (OLEDs) by C. T. Tang and S. VanSlyke, OLEDs have attracted close interest as a promising candidate for next-generation full-color displays and future solid-state lighting sources because of a number of advantages like high brightness and contrast, high luminous efficiency, fast response time, wide viewing angle, low power consumption, and light weight. The recombination of holes and electrons under electrical excitation typically generates 25% singlet excitons and 75% triplet excitons. For traditional fluorescent OLEDs, only 25% singlet excitons can be utilized to emit light, while the other 75% triplet excitons are generally wasted through nonradiative transition. By adopting noble metal phosphorescent complexes, an internal quantum efficiency (IQE) of 100% could be achieved by utilizing both the 25% singlet excitons and 75% triplet excitons. However, these phosphors usually contain nonrenewable and highcost iridium or platinum noble metals. Most recently, unity IQE has been readily achieved through noble metal-free purely organic emitters, such as thermally activated delayed fluorescence (TADF) emitters, hybridized local and charge-transfer state (HLCT) “hot exciton” emitters, binary- or ternary-mixed donor-acceptor exciplex emitters, and neutral p radical emitters, etc. In addition, the combination of conventional p-type hole-transport and n-type electron-transport materials in an appropriate device structure can also provide an uncommon efficiency. Both strategies are essential and attractive for high-performance and low-cost full-color displays and white OLED applications. This Research Topic mainly focus on this new generation of organic light-emitting materials and devices, including design, synthesis, and characterization of light-emitting organic molecules with tunable excited states, and their structural, electrical, and photophysical properties. Contributions relating to carrier transporting materials and corresponding device engineering are also included. Two mini reviews and thirteen original research articles by recognized academic experts in their respective fields are collected in this Research Topic, which will offer a broad perspective of noble metal-free organic light emitters, including conventional fluorescent emitters, TADF emitters, HLCT emitters, exciplex emitters, aggregation-induced emission (AIE) luminogens, and their corresponding devices. We believe this eBook should attract the attention of multidisciplinary researchers in the fields of materials science, organic synthesis, and electronic device engineering, especially for those engaged in OLED-related areas.

Download or read book Innovation Trends in Plastics Decoration and Surface Treatment written by Edward B Crutchley and published by Smithers Rapra. This book was released on 2014-08-11 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: The plastics industry is a major player for consumer items, notably for the automotive, consumer electronics and packaging industries, and is necessarily very active in innovation. As a result, moulded thermoplastics are achieving new heights in decorative appearance and quality. Many striking aesthetic effects are possible by employing new polymer blends coupled with a diverse range of decoration and surface treatment technologies. These can produce three-dimensional and tactile finishes, high definition images, flawless high gloss and metallic surfaces, as well as effects ranging from imitation materials, interferential colours, colour gradients, colour change and travel, gloss and matte combinations, and even acoustic or olfactory effects. Manufacturing processes to achieve these include several types of in-mould film, coating or decorating technique, relatively recent technologies to improve surface quality, as well as traditional separate decorating or coating processes such as dry offset; flexographic; inkjet; pad and screen printing; foil transfer; labelling; laser marking; plating; spray coating; and vacuum deposition. This unique book analyses and compares recent trends in each of over 20 types of mainstream manufacturing process and 10 classes of sensory effect they can produce. Supported by over 100 tables, a 3-year sampling of over 1,000 mentioned patent documents and hundreds of commercial developments helps to identify the main trends and their innovators, key innovative clusters and the most sought-after effects, as well as provide indications for the future.

Download or read book Innovation And Entrepreneurship Choice And Challenge written by Otto Chui Chau Lin and published by World Scientific. This book was released on 2018-02-26 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses practical issues of innovation and entrepreneurship. It first outlines the basic factors contributing to economic growth in the knowledge-based economy. Portraying wealth creation as taking scientific research results from lab to market, it identifies two interlinking components of the innovation process: turning scientific research to industrial technology and nurturing an eco-system conducive to technology business. Thus, it clarifies the position and role of four institutional players of the national innovation system: university (U), technology institute (T), government (G) and business (B). Making these players interact synergistically provides a fertile environment for innovation and entrepreneurship. The development of Silicon Valley, Hsinchu, Shenzhen and Singapore are illustrated as examples.For the technology entrepreneur, having a novel technology or unique product does not guarantee commercial success. It requires an effective business model, ability to execute business plan and entrepreneurial culture, all related to the soft power attributes of the entrepreneur team. The competitiveness of innovation and management of entrepreneurship are analyzed based on the concepts of Laozi and Confucius.Every entrepreneurship must learn to manage the challenges brought about by the changing business environment. The competitiveness and sustainability of a business is reflected by its ability to manage the change, both in bad and in good times. Every choice it makes will bring about new challenge. This is a definite, continuous and cyclic phenomenon occurring to all types of business. Some case examples of success or failure in managing challenges are given. They include: Alibaba Group, Ardentec IC testing, Cisco Systems, Delta Electronics, Eastman Kodak, Epistar HBLED, Fairchild Semiconductors, General Motors, GIANT carbon fiber bicycles, Tencent Holdings, TSMC, Volkswagen and others.This book is based on the author's practice and observation in technology and economic development especially in the Asia Pacific region during the post-1990s period. It is intended to be a reference of best practices for entrepreneurs, corporations and countries striving to make its mark in the knowledge-based economy.
