Tin dioxide (SnO2) is a wide-bandgap n-type semiconductor oxide widely used in gas sensing, optoelectronics, and transparent conducting applications. It is the material of choice for combustible gas detection (CO, methane, hydrogen) in industrial safety systems and consumer air quality monitors, and serves as a transparent electrode in displays and photovoltaic devices due to its optical transparency combined with electrical conductivity. SnO2 offers excellent chemical stability and lower processing temperatures than many alternatives, making it attractive for cost-sensitive mass production and integration into flexible electronics platforms.
