Application and preparation of ZnSe nanometerpowder by reduction process

Abstract
In this paper, we discussed the ZnSe synthesized from H2SeO4and Zn(Ac)2·2H2O as raw materials by coprecipitation process. WhenZn(Ac)2·2H2O dissolved in different solvents, the precipitated crystalline size and morphology of ZnSeO4were different after H2SeO4added.X-ray diffraction (XRD) method has been used to investigate the crystalline size, crystalline morphology, and phase structure of ZnSeO4.Then ZnSe was synthesized from ZnSeO4by reduction method using carbon monoxide. The structural variation of the ZnSe powder withdifferent annealing temperature was studied. The lowest temperature for the formation of single-phase ZnSe nanocrystals was found to be460 C and the average crystallite diameter in the powder annealed at 460 C was around 25 nm and it can be composed with organic glass.XRD and spectrum analysis showed that stable nanocomposite can be obtained from the mixture.

ZnO對ZnO納米棒陣列創(chuàng)建在鋅襯底上通過低溫水熱合成

摘 要
　　在本文中，我們討論了從H2SeO4鋅合成的ZnSe(Ac)2•2H2O為原料通過共沉淀過程。Zn(Ac)2•2H2O單獨溶解在不同溶劑中，加入H2SeO4之后析出的ZnSeO4結(jié)晶的大小和形態(tài)均不同。X-射線衍射(XRD)方法已經(jīng)被用于研究的結(jié)晶的大小，結(jié)晶形態(tài)和相結(jié)構(gòu)的ZnSeO4。然后，硒化鋅使用一氧化碳還原ZnSeO4合成的方法。在不同的退火溫度研究了ZnSe粉末的結(jié)構(gòu)變化。用于形成單相的ZnSe納米晶體的最低溫度被認為是460 ℃，粉末在460 ℃退火的平均晶粒直徑是約25 nm。XRD譜分析表明，穩(wěn)定的納米復(fù)合材料可從混合物中得到的。XRD譜分析表明，穩(wěn)定的納米復(fù)合材料可從混合物中得到的。
