Caractérisation structurale et optique De nanocristaux de ZnO

Abstract

This work to study the structural and optical ZnO nanocrystals For the preparation of nano- zinc oxide was confused by Material: LaCetate Zinc dihydrate , citric acid For the preparation of nano ZnO by material : Zinc LaCetate dihydrate , citric acid For the preparation of thin film nano composite material was : , The nano ZnO powder , THF ( tetrahydrofuran ) , the léthanol PMMA After preparing thin layer were placed under a UV radiation Structural study of this course are made by thin film X-ray diffraction to determine the size of nanoscale crystals ZNO Preliminary study using the optical absorption in the UV range of the following thin film showed absorption edge shift to higher energies and this is due to the small size of the nanocrystals ZNO The study by the program that the samples his boots intense emission in the , emission of visible and near UV makes this material prepared from the elements eligible for the use of applications in the field of optical and electrical .
