Basic information: 1.Purity :99.99%--99.999% 4n 5n ; 2. Cas no.: 12024-21-4; 3. Main application: phosphor in light emitting diodes Characteristics: Gallium trioxide is a white powder produced from the element's metallic form. Applications: Gallium trioxide (ga2o3) is used as a phosphor in light emitting diodes, as well as in lasers and other luminescent materials. Although it can be prepared in both a and ß crystal phases, the stable ß-ga2o3 is more commonly used in commercial applications .
