Abstract:  

 

There is a great deal of interest in finding new synthetic routes to prepare nano-crystallites.

This paper reports in situ preparation of CdSe nanoparticles using poly(vinyl alcohol) [PVA]   as matrix by using chemical route.

 XRD analysis revealed that CdSe-PVA nano- composite with a small size and narrow size distribution were obtained. The XRD studies show the formation of hexagonal CdSe/PVA particles with an average size of 11nm.

 Photoluminescence properties of CdSe/PVA with varying polmer concentration are reported.

The PL peak was observed at 510 nm in photoluminescence spectrum.
