Luminescence properties of Tb-activated yttrium gallium garnet phosphors

Comparison of luminescence properties between electron-excited and uv-excited yttrium gallium garnet: Tb phosphors is reported. Although the thermoluminescence and phosphorescence in both cases are quite alike once traps are filled, an apparent difference in the behavior of trap filling has been observed. Small addition of V2O3 to these phosphors revealed a unique effect on luminescence properties either with the electron excitation or with the uv excitation. © 1983.
