Problems solved by technology

In recent years, the more transparent conductive materials studied are ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide), especially ITO. However, since indium in ITO is a rare metal, it is expensive. The wide application of ITO is limited, and ATO has the disadvantages of poor thermal insulation and low visible light transmittance when used for thermal insulation of architectural glass

Abstract

The invention discloses ytterbium-doped bismuth-doped tin oxide (BTO) nano powder, and a preparation method and application thereof, and in particular relates to an ultrasonic chemical method for preparing the ytterbium-doped BTO nano powder. Bismuth and ytterbium are subjected to solid solution by the ultrasonic chemical method to enter a tin dioxide (SnO2) matrix. The method particularly comprises the following steps of: dissolving bismuth salt and ytterbium salt in a certain doping ratio into tin salt solution at certain concentration; adding a proper amount of dispersing agent; stirring until the raw materials are dissolved completely; adding a certain amount of urea and mixing the solution uniformly; washing by using argon; performing chemical reaction at a certain temperature and under ultrasonic radiation; and ageing, washing, drying and calcining to obtain the ytterbium-doped BTO nano powder. The invention provides the idea that the ytterbium is doped into the BTO powder for the first time, so the absorptivity of the powder on infrared rays is improved. The ytterbium-doped BTO nano powder has small grain size, is dispersed uniformly and hardly agglomerates; and the preparation process is simple, and high in efficiency and reproducibility, and contributes to industrialization.

Description

technical field [0001] The invention relates to the field of nanometer materials, in particular to an ytterbium-doped BTO nanopowder and its preparation method and application. Background technique [0002] Transparent conductive materials are new multifunctional materials in the 21st century. Due to their excellent electrical and optical properties, they are widely used in optoelectronic display devices, transparent electrodes, solar cells, thermal windows, catalysis and other fields. In recent years, the more transparent conductive materials studied are ITO (tin-doped indium oxide) and ATO (antimony-doped tin oxide), especially ITO. However, since indium in ITO is a rare metal, it is expensive. This limits the wide application of ITO, and ATO has the disadvantages of poor thermal insulation and low visible light transmittance when used for thermal insulation of architectural glass. [0003] Therefore, the prior art still needs to be improved and developed. Contents of t...
