Indium (III) oxide - Introduction
As an n-type wide band gap transparent semiconductor nanomaterial, indium trioxide has many excellent properties and has been applied in many fields, such as ultra-sensitive gas sensors, solar cells, liquid crystal displays and building glass heating materials. The unsurface-modified indium trioxide nanocrystals and the surface-modified indium trioxide nanocrystals and nanoscale have strong fluorescence properties and visible light transmission properties. They are used in different media such as chloroform, petroleum ether, and water. It has good dispersibility and can be used as a biofluorescent indicator and glass transparent coating.
Uses are mainly used as battery raw materials, fluorescent screens, glass, ceramics, chemical reagents, etc.
Uses Used as a material for spectral pure reagents and electronic components, etc.
