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 503 nm under 147 and 254 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 147 nm and these could be tentatively interpreted in terms of optical properties of host compounds and co-doped ions.
