Abstract
The vaccum-ultra-violet (VUV)- and UV-excited luminescent properties of MgGa2O4:Mn2+ phosphor with various co-dopants were investigated. Spinel-structured manganese-activated magnesium gallate exhibited intense green emission with the spectrum centered at 503Â nm under 147 and 254Â nm excitation induced by the transition from the lowest excited state to the ground state, 4T1-6A1, of the tetrahedral-sited Mn2+. With optimized incorporation ranges, Eu3+, Ce3+ and Al3+ co-doping, enhanced the overall fluorescence efficiency under 147Â nm and these could be tentatively interpreted in terms of optical properties of host compounds and co-doped ions.
