The Microhardness and Photoluminescence properties of ZnSe/PVA and CdSe/PVA nanocomposite films were investigated with different ZnSe and CdSe content in polyvinyl alcohal (PVA). These nanocomposite samples were prepared by environmental friendly chemical method. The prepared samples were characterized by using X-Ray Diffraction (XRD), Atomic force microscope (AFM).
The X ray diffraction revealed cubic structure of ZnSe/PVA and CdSe/PVA with particle size less than a few nm. Photoluminescence (PL) spectrum shows blue shift as compared to the bulk and intensity is found to increase with reducing particle size. The microharness studies showed these nanocomposite films becomes harder with decrease in nanoparicle size in PVA matrix.
These films may be useful for their potential application in anti-reflection coating, display devices and optical sensors.
