| 英文摘要 | The photoluminescence behavior of a high efficient red phosphor Gd3B(W,Mo)O-9:Eu3+ designed according to crystal structure and electronic structure is presented in detail. The substitution of isolated WO6 group by MoO6 makes the absorption band edge extend from 360 nm to 440 nm, as designed to fit the excitation of near ultraviolet (NUV) LED chip, which could be interpreted by the density functional theory calculations. The extreme low symmetry (C-1) of Eu3+(Gd3+) site enables Eu3+ ion to show dominant electronic dipole transition D-5(0) -> F-7(2) (similar to 616 nm) with five apparent splitting peaks according to group theory, which is almost 10 times stronger than that of commercial Y2O2S:Eu3+ upon similar to 385 nm excitation. The outstanding thermal stability of photoluminescence of this phosphor up to 523 K may probably be owed to the energy transfer from isolated MoO6 groups to the well-dispersed Eu3+ ion separated by BO3 groups. The performance of NUV white-LEDs package fabricated with a blue, green and this red phosphor is also demonstrated. It shows high color stability of the white light (CIE coordinate (0.320, 0.349), CCT 6031K, at 20 mA) under the DC drive current varied from 20 mA to 350 mA, verifying the potential application of the red phosphor in tri-color phosphors coated white-LEDs.
