Indium oxide also known as indium sesquioxide is a yellow colored ceramic like material which is insoluble in water. It is an n-type semiconductor and is therefore used as a resistive element in integrated circuits. Indium oxide can be doped with tin dioxide to form indium tin oxide which is used in display technologies such as OLED, plasma electroluminescent, electrochromatic display and LCD. It is used as an antistatic indium oxide coating, in photovoltaic solar cells, aircraft windshields, EMI shielding and nanowires. Indium oxide finds several applications in the electronics industry owing to its semiconductor characteristics.
