1. FTO conductive glass is fluorine-doped SnO2 transparent conductive glass (SnO2: F), referred to as FTO.
2. SnO2 is a wide band-gap oxide semiconductor that is transparent to visible light, with a band gap of 3.7-4.0eV, and has a regular tetrahedral gold red structure. After being doped with fluorine, the SnO2 film has the advantages of good light transmittance to visible light, large ultraviolet absorption coefficient, low resistivity, stable chemical properties, and strong resistance to acid and alkali at room temperature.
