摘　　要：本文用高温固相法制备KAlSi_(3)O_(8):Tm^(3+)样品,利用近紫外光激发样品,观察到在452 nm处存在强烈的蓝光发射,随着Tm^(3+)离子浓度的增加,样品发光强度先增强后减弱,当掺杂浓度达到1%时,样品的发光强度达到最佳,表明存在浓度猝灭效应.向样品中掺杂电荷补偿剂Li^(+)离子,样品在452 nm、757 nm处的发光强度增长了2.11倍.该结果预示该样品在固态照明领域,特别是蓝色荧光粉的应用方面具有广阔的前景.In this paper,KAlSi_(3)O_(8):Tm^(3+)samples were prepared by high-temperature solid-state method.When the samples were excited by near-ultraviolet light,a strong blue emission at 452 nm was observed.With the increase of Tm^(3+)ion concentration,the luminescence intensity of the samples first increased and then decreased.When the doping concentration reached 1%,the luminescence intensity of the samples reached the optimum,indicating the existence of concentration quenching effect.By doping the charge compensator Li~+ions into the samples,the luminescence intensities at 452 nm and 757 nm increased by 2.11 times.This result indicates that the samples have broad prospects in the field of solid-state lighting,especially in the application of blue phosphors.
