摘要：
Energy transfer between Ce3+ and Tb3+ dopants in alkaline earth (Ba, Sr or Ca) sulphate phosphors is investigated. Among these three phosphors, CaSO4:Ce3+ Tb3+ showed maximum Tb3+ green emission on excitation with UV light. Photoluminescence measurements reveal that the emission intensity from CaSO4:Ce3+, Tb3+ is comparable with that of the commercial green lamp phosphor Ce0.65Tb0.35MgAl11O19. Optimum concentrations of dopants in CaSO4:Ce3+, Tb3+ are 0.2 mol% each and the optimum sintering treatment following re-crystallisation is 600 degreesC for I h duration. The effect of charge compensator in all the three phosphors is also studied. (C) 2003 Elsevier B.V. All rights reserved.
