Abstract. There is a great deal of interest in finding new synthetic routes to prepare nanocrystallites.
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 polymer concentration are reported.
The PL peak was observed at 510 nm in photoluminescence spectrum.
