Electroluminescence emission from indium oxide and indium-tin-oxide

Abstract
Electroluminescence emission from indium‐tin‐oxide (ITO) and indium oxide films incorporated in a Si‐rich SiO2‐SiO2‐ITO (In2O3) multiple‐layer structure is reported. The light emitted has a peak at approximately 3.3 eV for ITO and at 2.6 eV for In2O3. The intensity of the light is found to depend on the applied electric field.
