摘要：

The Ho3+/Tm3+ co-doped LiYb(MoO4)(2) phosphors were synthesized by solid state reaction. The crystal phase was characterized by the X-ray powder diffraction. The blue emission of Tm3+ at 475 nm and the green and red emissions of Ho3+ at 545 and 660 nm, respectively, are observed under the laser excitation at 975 nm. The tunable white upconversion luminescence is realized by varying Ho3+ and Tm3+ concentrations in LiYb(MoO4)(2). Bright white upconversion emission is observed in 0.2%Ho3+/0.8%Tm3+ co-doped LiYb(MoO4)(2). Based on laser pump power, upconversion emission mechanism and population process are discussed in detail.
