摘要：

A new phosphor, Eu3+ doped 3CdO-Al2O3-3SiO(2) (CAS:Eu3+), is prepared by a convenient sol-gel method. Under excitation either into the L-5(6) state with 394 nm or the D-5(2) state with 464 nm., the phosphor gives a red emission at 610 nm originating from the D-5(0) -> F-7(2) transition of Eu3+. The luminescence properties compared with YAG:Ce3+ and Y2O3:Eu3+ are studied. The red emission of CAS:Eu3+ is about 3 times stronger than that of commercial Y2O3:Eu3+. The high color saturation (the chromaticity index is x = 0.6209, y = 0.3461) and the low thermal quenching effect make phosphor CAS:Eu3+ a promising candidate for the phosphor-converted white LEDs.
