Synthesis and Characterization of ZnSe Nanoparticles by Co-precipitation Method
A. Jafar Ahamed*, K. Ramar, P. Vijaya Kumar

Zinc selenide nanoparticles (ZnSe NPs) have been synthesized by simple and inexpensive co-precipitation method using polyvinylpyrrolidone (PVP) as capping agent. The morphology and structure of ZnSe nanocrystals have been characterized by using field emission scanning electron microscopy (FE-SEM), X-ray diffraction studies (XRD), ultraviolet-visible spectroscopy (UV-vis), Fourier transform infrared spectrum (FTIR) and photoluminescence spectroscopy (PL). XRD study evident that the synthesized ZnSe nanoparticles were cubic in structure. Strong blue shift absorption (371 nm) is observed from UV–visible spectrophotometry. The presence of hydrazine monohydrate and polyvinylpyrrolidone in the ZnSe nanoparticles is confirmed by the FTIR spectrum. The enhanced luminescence property is measured from photoluminescence spectrophotometry.
