In2O3
semiconductor· In2O3
Indium oxide (In₂O₃) is a transparent conducting oxide semiconductor with a wide bandgap, combining electrical conductivity with optical transparency in the visible spectrum. It is widely used in optoelectronic and photovoltaic applications, particularly as a transparent electrode material in liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs), and thin-film solar cells, often alloyed with tin (ITO) to enhance conductivity. Engineers select In₂O₃-based materials when applications require simultaneous light transmission and electrical function, though the material's indium content and cost drive consideration of alternative transparent conducting oxides in cost-sensitive applications.

Regulatory Screening
Environmental
Export Control
RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
