Indium oxide usually denotes indium(III) oxide, , a solid chemical compound of indium and oxygen. Formal oxidation states of for indium and for oxygen give charge balance: . The formula expresses the elemental ratio; it does not imply discrete molecules in the solid.[ref]

Doping this oxide with tin produces the material family indium tin oxide, used for transparent conducting layers. Electrical and optical performance depend on charge-carrier density and preparation, so knowing the host compound's formula alone does not specify a film's conductivity.[ref]

Indium tin oxide 2026-11-05
Indium tin oxide is a conducting oxide material based on indium oxide doped with tin. It is valued for combining substantial electrical conductivity with transmission of visible light, allowing a thin layer to function as an electrode through which light can pass. Its composition is not represented by one universal stoichiometric formula.[ref]
The two properties probe different responses. Direct-current conduction measures mobile charge carriers, while optical transmission depends on frequency-dependent absorption and reflection as well as film thickness. Increasing carrier density can therefore change the optical response together with conductivity. Measurements of Hall effect and optical resonances help connect the electrical and optical descriptions of the same film.[ref]
