摘要

本文报道了以PVA为稳定剂，采用环保、安全、廉价、简便、无有机金属的合成化学路线原位制备ZnSe-PVA纳米复合膜。XRD研究表明，在PVA基体中形成了平均尺寸为~7nm的立方ZnSe纳米颗粒。由UV-VIS吸收光谱的吸收边缘确定的能带隙表明，带隙随着粒径的减小而增大。还报道了ZnSe/PVA在不同浓度ZnSe含量下的折射率和光致发光（PL）等光学性质。蓝移是由于PVA基质中ZnSe纳米颗粒的尺寸减小引起的。

Synthesis and Characterization of ZnSe/PVA nanocomposites for optical devices

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.
