Yellow lighting upconversion from Yb3+/Ho3+ co-doped CaMoO4
Source abstract
Abstract
Abstract Yellow upconversion (UC) luminescence is observed in Ho 3+ /Yb 3+ co-doped CaMoO 4 synthesized by complex citrate-gel method. Under 980 nm excitation, Ho 3+ /Yb 3+ co-doped CaMoO 4 exhibited yellow emission based on green emission near 543 nm generated by 4 F 4 , 5 S 2 → 5 I8 transition and strong red emission around 656 nm generated by 5 F 5 → 5 I 8 transition, which are assigned to the intra 4f transitions of Ho 3+ ions. The optimum doping concentration of Ho 3+ and Yb 3+ was investigated for highest upconversion luminescence. Based on pump power dependence, upconversion mechanism of Ho 3+ /Yb 3+ co-doped CaMoO 4 was studied in detail.
