Abstract

The invention relates to a preparation method of a Cu2-xSe chip. The preparation method comprises following steps: (1) preparing a copper precursor solution; (2) preparing a selenium precursor solution; (3) performing filling reflux to generate the Cu2-xSe chip; and (4) washing the Cu2-xSe chip and performing liquid removing to obtain the Cu2-xSe chip in the invention. In the preparation method, a polyol is employed as a solvent, ethanediamine is employed as a reducing agent, and an inorganic copper salt is employed as a precursor so that dissolution is easy to carry out and the preparation method is low in requirement on devices. Not only is a problem of environmental pollution solved but also a product preparation cost is reduced. By means of a solution chemical synthesis method under normal pressure, the preparation method is simple in technology, is easy to control, is less in discharge and is good in safety. The Cu2-xSe chip is good in dispersing performance, is uniform in appearance, is high in crystallization degree and is suitable for large-scale industrial production.

Description

technical field [0001] The invention belongs to the technical field of metal selenium compound materials, in particular to a Cu 2-x Preparation method of Se nanowafers. Background technique [0002] In recent years, nanoscale inorganic semiconductors have attracted more research interest due to the effect of size and shape on physical and chemical properties. Metal selenide materials are promising for applications in optics, optoelectronics, catalysts, and biosensors (see Lijuan Zhao, Linfeng Hu, and Xiaosheng Fang, Adv.Funct.Mater.22, 1551 and S.P.Gubin, N.A.Kataeva, and G.B. Khomutov, Russian Chemical Bulletin. 54, 827). [0003] Cu 2-x Se, as a group I–VI semiconductor compound, is a P-type semiconductor with unique optoelectronic properties. Because of its wide application in electronic and optoelectronic equipment, it has attracted everyone's attention. Copper selenide is widely used in solar cell filters, photoelectric conversion, thermoelectrics, nanoswitches, su...
