ABSTRACT

Up-conversion (UC) luminescence properties of polycrystalline Er 3+ /Yb 3+ doped NaGd(MoO4)2 phosphors synthesized by a simple solid-state reaction method were investigated in detail. Used to 980 nm excitation (InfraRed area), Er 3+ /Yb 3+ co-doped NaGd(MoO4)2 exhibited very weak red emissions near 650 and 670 nm, and very strong green UC emissions at 540 and 550 nm corresponding to the infra 4f transitions of Er 3+ ( 4 F9/2, 2 H11/2, 4 S3/2)→Er 3+ ( 4 I15/2). The optimum doping concentration of Er 3+ , Yb 3+ for highest emission intensity was determined by XRD and PL analysis. The Er 3+ /Yb 3+ (10.0/10.0 mol%) co-doped NaGd(MoO4)2 phosphor sample exhibited very strong shiny green emission. A possible UC mechanism for Er 3+ /Yb 3+ co-doped NaGd(MoO4)2 depending on the pump power dependence was discussed.
