PVA passivated ZnSe nanorods have been synthesized using the solvothermal method. XRD analysis of the synthesized nanorods validates the cubic zinc blende structure with average particle size of 14 nm, and SEM analysis confi rms the formation of rods having a wide range of lengths. A twin nanorod along with a typical nanostructure of rods has been observed in SEM micrographs. The optical characterization of the synthesized nanorods has been made using UV-Vis and photoluminescence spectroscopy. An energy gap of 3.89 eV has been observed, which is blue shifted from the bulk ZnSe. The dielectric study of ZnSe nanorods has been also made and reported.

Pva包覆的Znse纳米棒的光学和介电特性

使用溶剂热法合成了PVA钝化的ZnSe纳米棒。合成纳米棒的XRD分析证实了立方锌混合结构的平均粒径为14 nm，而SEM分析则证实了各种长度的棒的形成。在SEM显微图中观察到双纳米棒以及典型的棒纳米结构。合成的纳米棒的光学表征已使用UV-Vis和光致发光光谱法进行了。已经观察到3.89eV的能隙，其从块状ZnSe发生蓝移。ZnSe纳米棒的介电研究也已经完成并报道。
