Abstract: The nanocomposite films of ZnSe nanocrystals in polyvinyl alcohol (PVA) matrix were synthesized by environmental friendly chemical method for optoelectronic Applications. These composites were characterized by X-ray diffraction and AFM which indicates the hexagonal crystalline structure with particle size up to a few nm. The Particle size is found to decrease by increasing PVA Concentration. The photoluminescence properties of these composite films with varying concentration of PVA and Zn have been investigated.
This may be useful for their potential application in anti-reflection coating, display devices and optical sensors. Micro Hardness of these nanocomposites was also measured by Vicker hardness tester and its dependence with varying load and mechanical behavior of samples was discussed.
