Available in PDF, EPUB and Kindle. Book excerpt: Cet ouvrage, presente les proprietes optiques lineaires, non lineaires des semi-conducteurs II-VI, proprietes modifies, quand on passe du massif a un materiau nanometrique, met en exergue l'interet, les avantages que procurent ces materiaux dans leurs applications comme doubleurs et tripleurs de frequence, compare a d'autres materiaux usuels. Chapitre I: expose la problematique, l'actualite du travail sur les materiaux nanocomposites. Il donne un apercu sur les proprietes optiques des nanocomposites a base de semi-conducteurs, fait apparaitre les raisons justifiant les materiaux adoptes pour la fabrication des nanocomposites. Chapitre II est dedie aux methodes d'elaboration des materiaux nanocomposites. Chapitre III: presente les differentes techniques d'analyses: DRX, spectroscopie UV-visible, luminescence, IR, Raman, AFM, MEB. Chapitre IV: presente les concepts de non linearite, la generation du second, du troisieme harmonique, decrit les differents modeles theoriques. Le chapitre V dedie a l'experimentation des materiaux nanocomposites, comporte: La discussion des resultats"
