Available in PDF, EPUB and Kindle. Book excerpt: Absorption spectra were used to determine the effect of modifier ions on the splitting and relative intensity of neodymium spectral terms in germanate and other glasses. The behavior of spectral components is related to the degree of inhomogeneous broadening and changes in the site symmetry of the neodymium ion. A similarity between the wavelength position of neodymium term levels and their total width in glasses and crystalline neodymium oxide has been observed. Fluorescence spectra for neodymium, erbium, and holmium ions in sodium germanate glass are reported and the absorption lines involved in excitation with both lamp and laser sources discussed. The lines of an argon-ion laser are found to be more convenient and powerful sources for the excitation of rare earth ion fluorescence than mercury vapor or tungsten lamp sources. The energy level diagram of neodymium in sodium germanate glass was determined from absorption and fluorescence peak spectra. A relationship between the strength of infrared absorption bands involved in cross-relaxation processes and the extent of neodymium fluorescence quenching was observed. Fluorescence conversion efficiencies comparable or higher than those of commercial laser glasses are found for neodymium in sodium germanate glass by both laser and lamp excitation methods. Germanate glasses show good potential as laser hosts for a number of rare earth ions. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This text describes the technique of optical spectroscopy applied to problems in condensed matter physics. It relates theoretical understanding to experimental measurement, including discussion of the optical spectroscopy of inorganic insulators, with many illustrative examples. Symmetry arguments are developed from a formal group theoretical basis and are frequently used, and a special effort is made to treat the subject of lattice vibrations and to show how these can affect the spectroscopic properties of solids. The elements of laser theory are developed, and the authors also explore the use of optically detected magnetic resonance techniques for the investigation of semiconducting materials.

Download or read book Spectroscopic Studies of Rare Earth Doped Phosphate Glasses written by Pramod Kothari and published by LAP Lambert Academic Publishing. This book was released on 2014-10-01 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Glass is the most important substrate material suitable for fabrication of passive and active integrated optical components. The refractive index of a glass substrate is very close to that of the optical fibers (n=1.48), which minimizes the coupling losses between glass waveguides and optical fibers. Glass has excellent transparency in the visible and near infrared spectral regions and can easily be made in different sizes and shapes with very high homogeneity. As an amorphous material distinct from crystals, it is easier to produce polarization insensitive integrated optical components in glass. In addition, Glass has a high threshold to optical damage; it is mechanically very rigid and relatively inexpensive. Glass is also suitable host for rare earth ions. This has allowed for the fabrication of optical amplifiers and lasers.

Book excerpt: In this collection, chalcogenide glasses doped with rare earth elements are proposed as particularly attractive materials for applications in integrated photonics. The opening chapter is dedicated to reviewing the studies on optical properties of (GeS2)100?x (Ga2S3)x (x=20, 25 and 33 mol%) glasses, doped with Er2S3 in a wide range from 1.8 to 2.7 mol%, by absorption and photoluminescence (PL) spectroscopy. The authors focus on features in absorption, emission, and local ordering and their derivatives as a function of excitation wavelength, Er3+ doping level, Ga content and temperature for the (GeS2)80 (Ga2S3)20 host composition. Next, to demonstrate the technological importance of optical devices with unique properties derived from rare-earth activated glasses, the authors reviewed some fundamental aspects of rare-earth doped optical glassy devices where the light is confined in different volumes or shapes, namely fibers, monoliths, film/coatings and microspheres. Rare-earth activated glasses are often used as components in integrated optical circuits. Later, optical characteristics of semiconducting crystals with layered structure due to quantization effects in the architecture governed by the atomic arrangements are discussed. In order to study the microscopic optical processes of these materials, the phenomenological research from photoluminescence studies (PL) was determined to be essential to those established by conventional bulk materials. Layered crystals such as Cs3Bi2I9, BiI3 and PbI2 have been considered for reporting the PL spectra in order to discuss relevant information concerning photo-induced charge carrier separation and also the radiative and non-radiative recombination dependent on deep or shallow trap states. Additionally, the photoluminescence properties of composites based on conjugated polymers and carbon nanoparticles of the type carbon nanotubes, reduced graphene oxide and fullerenes are analyzed. A review is presented on the photoluminescence properties of various macromolecular compounds, for example poly(para-phenylenevinylene), poly(3-hexylthiophene), poly(3,4-ethylenedioxythiophene-co-pyrene), polydiphenylamine and poly(9,9-dioctylfluorenyl-2,7-diyl) as well as effects induced by the carbon nanoparticles mentioned above. The following chapter focusses on fullerenes, carbon nanotubes, graphene, graphene oxide, graphene and carbon quantum dots. Firstly, the general physical and chemical properties of different carbon-based nanomaterials are presented, such as the crystalline structure, morphology and chemical composition. Additionally, the possibilities of application of carbon-based nanomaterials due to its PL properties are analyzed. The concluding chapter focuses on coordination polymers (CPs) / metal-organic frameworks (MOFs) containing metal ions from d and 4f series and a plethora of organic ligands, the resulted compounds showing remarkable photoluminescence properties with different applications in the field light emitting devices (LEDs), biosensors in medical assays, sensors for identifying certain species (molecules, ions) and so on.
