Abstract

Host sensitized up-conversion phosphors Yb₂O₃:Er³⁺ with sphere-shaped morphology were prepared by a urea-based homogeneous precipitation process. The effects of sintering temperature on the structure and morphology of particles were investigated. The up-conversion emission spectra of Yb₂O₃:Er³⁺ with 980 nm excitation exhibit the green and red double bands, attributing to ²H_11/2/⁴S_3/2→⁴I_15/2 and ⁴F_9/2→⁴I_15/2 transitions of Er³⁺ ions, respectively. The possible up-conversion mechanism and processes were also proposed.
