Synthesis and Characterization of ZnSe/PVA nanocomposites for optical devices

This is the authors' abstract. We don't add key points for this paper.

This paper reports in situ preparation of ZnSe-PVA nanocomposite film using ecofriendly, safe, inexpensive, facile and non-organometallic synthetic chemical route, with PVA as the stabilizing agent. The XRD studies showed the formation of cubic ZnSe nanoparticles in PVA matrix with an average size of ~7 nm. Energy band gap determined by absorption edge of UV-VIS absorption spectra revealed increase in band gap with decrease in particle size. The optical properties like Refractive index and Photoluminescence (PL) of ZnSe /PVA with varying concentration of ZnSe content are also reported. The blue shift was found due to size reduction of ZnSe nanoparticles in PVA matrix.
