General description

Cadmium oxide (CdO) is a semiconducting material with high conductivity which isoptically transparent in the electromagnetic spectra. It has a direct bandgap of 2.28 eV and can form a single crystal material by metal organic vapor phase epitaxy (MOVPE) growth.[86]

Application

CdO can be used in the synthesis of cadmium selenide quantum dots for potential applications in photocatalysis.[67] It is used as a transparent conducting oxide (TCO) which can further be used in a variety of opto-electronic devices.[88][89]
