Upconversion emission in multi-doped glasses for full colour display

摘要

Upconversion luminescence characteristics of a multi-rare-earth-doped 0.05K(2)O-0-1ZnO-0.1BaO-0.2PbO-0.2GeO(2)-0.35TeO(2) glass have been investigated under 976 nm excitation for potential use in full colour displays. Two luminescence ions, Er and Trn, 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 ran upconversion emissions simultaneously increase.
