Used in the production of indium-containing semiconductors, particularly in thin-film transistors and transparent conductive coatings for displays and solar cells. Serves as a fluorinating agent in organic synthesis due to its ability to transfer fluoride ions under mild conditions. Employed in the preparation of solid-state batteries, where it enhances ionic conductivity in electrolyte materials. Also utilized in optical coatings and infrared-transmitting materials owing to its low refractive index and transparency in the ultraviolet to mid-infrared range. Plays a role in doping processes for phosphors and luminescent materials used in lighting and display technologies.
