摘要

Y_2(MoO_4)_3:Er~3/Yb~3 phosphors with fixed (varied) Er~3 and varied (fixed) Yb~3 concentrations were synthesized by a conventional solid-state reaction. The crystal structure of the phosphors was characterized by means of X-ray diffraction (XRD). Upon 980 nm excitation, very weak blue emission, and strong green and red upconversion emissions centered at 485, 525, 545 and 656 nm were observed. The two-photon process was confirmed to be responsible for both the green and red upconversion emissions. The effects of green upconversion emission intensity ratio (~2H_(11/2)→~4I_(15/2) versus ~4S_(3/2)→~4I_(15/2)) and the integrated upconversion emission intensity on the Yb~3 and Er ~3 concentrations were studied.
