摘要：

A phosphor Eu(3+)doped Cd3Al2Si3O12 was prepared by a convenient sot-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 D-5(0)-> F-7(2) transition of Eu3+. The red emission of Cd3Al2Si3O12:Eu3+ is about 2.4 times stronger than that of Y2O3:Eu3+. The low thermal quenching effect makes phosphor Cd3Al2Si3O12:Eu3+ a promising candidate for the phosphor-converted white LEDs.
