AbstractGdF3:Er3+,Yb-3 with Er3+ ion of 3% and Yb3+ ion concentration of 10%, 20% have been prepared by a hydrothermal method. The results of XRD show that all the samples are of an orthorhombic structure. The average crystallite sizes estimated by Scherrer formula are 28 and 26 nm for Gd0.87Yb0.10Er0.03F3 and Gd0.77Yb0.20Er0.03F3, respectively. The Upconversion luminescence spectra of the samples have been studied under 980 run laser excitation. The results show that the green and red upconversion emission can be attributed to the H-2(11/2),S-4(3/2) -> 4I(15/2) and 4F(9/2) -> 4I(15/2) transitions of Er3+, respectively. The intensity of green emission Is stronger than that of red emission for two samples. The ratio of the intensity of green to red emission is related to Yb3+ ion concentration. The possible. upconversion luminescence mechanisms in Gd0.87Yb0.10Er0.03F3 and Gd(0.77)Ybn(0.20)Er(0.03)F(3) are discussed.
