· JVASP-9410· CdGa2O4

CdGa2O4 is a cadmium gallium oxide ceramic compound belonging to the spinel family of oxides, characterized by a crystalline structure with mixed metal cation coordination. This material is primarily of research interest for optoelectronic and photonic applications, particularly in UV and visible light detection and emission systems where its wide bandgap and optical transparency are advantageous. While not yet widely deployed in mainstream industrial production, CdGa2O4 represents an important candidate material for next-generation semiconductor devices, scintillators, and photodetectors where conventional alternatives face performance or cost limitations.
