Show affiliationsUpconversion luminescence characteristics of a multi-rare-earth-doped 0.05K2O–0.1ZnO–0.1BaO–0.2PbO–0.2GeO2–0.35TeO2 glass have been investigated under 976 nm excitation for potential use in full colour displays. Two luminescence ions, Er3+ and Tm3+, were used as blue, green and red emitters to control the colour of the emitted light. Sensitizer ions, Yb3+, were used to increase the upconversion emission intensity. With the substitution of Er3+ for Tm3+, the intensities of the blue, green and 657 nm upconversion emissions simultaneously increase.
