We all are working in the field of nanoscience and technology. If any member want to take help from our work/ university then we welcome him/her.We should interact with each other at this platform.

The Luminescence properties of ZnSe/PVA and CdSe/PVA were investigated with different Zn²⁺and Cd²⁺ content and with different PVA concentrations. 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) and photoluminescence (PL).

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.
