White up-conversion luminescence properties in Yb3+/Ho3+/Tm3+ tri-doped LiGaW2O8 phosphors
Source abstract
Abstract
Abstract Monoclinic Yb3+-Tm3+-Ho3+ tri-doped LiGaW2O8 phosphors were prepared by the high temperature solid-state method. Upon the excitation of 980 nm, up-conversion (UC) blue emission in Tm3+/Yb3+ co-doped and green and red emissions in Ho3+/Yb3+ co-doped LiGaW2O8 were observed, respectively. Bright white luminescence could be obtained by changing the doped concentrations of Tm3+ ions in Tm3+/Ho3+/Yb3+ co-doped LiGaW2O8. Moreover, based on the power dependence of the luminescence intensity, the UC mechanisms were studied. The results demonstrate that the multi-colors of the LiGaW2O8:Tm3+,Ho3+,Yb3+ could be used in the fields of three-dimensional displays, solid-state lighting, and backlighting such as the white light generation.
