General description

Indium(III)oxide is a versatile compound with significant applications in electronics,optics, and materials science. It is widely employed in the synthesis of transparentconducting oxides (TCOs), particularly for flat-panel displays, and solarcells, due to its electrical conductivity and optical transparency. Insemiconductor technology, it is used for making indium tin oxide (ITO),enhancing the performance of electronic devices, and is sensitive to variousgases, making it suitable for gas sensing applications, particularly indetecting hazardous gases.
