摘要

The emission properties of ZnGa_(2)O_(4):Mn phosphors have been compared for samples prepared via an oxalate gel route and those prepared via a conventional solid synthetic route. The firing conditions were found to be critical for obtaining good emission on account of possible redox processes involving both the Mn~(2+) activator ion and the host ZnGa_(2)O_(4) lattice itself. An interesting reversible shift was observed for the CIE coordinates of the cathodo-luminescence when the energy of the exciting electron beam was varied. This is explained by increased vibronic excitation of the ZnGa_(2)O_(4):Mn phosphors at higher electron beam energies, resulting in a greater relative contribution of the vibronic side bands to the green emission.
