摘要	Dependences of the spectral profiles on the both Tm3+- and Yb3+ additive amounts were presented. Further, the temporal evolution of Tm3+ luminescence in the nanocrystals was explored. Enhanced ultraviolet emissions with Tm3+ upconversion were investigated in the Y0.800-xF3:Yb-0.200(3+), Tm-x(3+), nanocrystal samples following excitation with 980 nm. The emissions can be attributed to the transitions of (1)G(4) -> H-3(6), D-1(2) -> F-3(4) or H-3(6) and (P-3(0) and I-1(6)) -> F-3(4) or H-3(6). A detailed energy-transition scheme was proposed and described well the ultraviolet-enhanced upconversion of Tm3+ and the energy-transfer processes from Yb3+ to Tm3+ based on energy-matching conditions.
