Effect of Yb3+ and Tm3+ concentrations on blue and NIR upconversion luminescence in Yb3+, Tm3+ co-doped CaMoO4
Source abstract
Abstract
Abstract Polycrystalline Tm 3+ /Yb 3+ co-doped CaMoO 4 UC phosphors were successfully synthesized by a complex citrate-gel method and their upconversion (UC) luminescence was investigated. Under excitation at 980 nm, Tm 3+ /Yb 3+ co-doped CaMoO 4 showed bright blue emission near 475 nm generated by the 1 G 4 → 3 H 6 transition and strong NIR UC emission around 796 nm generated by the 3 H 4 → 3 H 6 transition, with weak red emission near 650 nm due to the 3 F 2 → 3 H 6 transition. The optimum doping concentrations of Tm 3+ and Yb 3+ for the highest UC luminescence were investigated, and the related UC mechanism of Tm 3+ /Yb 3+ co-doped CaMoO 4 depending on pump power was studied in detail.
