摘要

用化学共沉淀法一次煅烧工艺制备Ce，Pr:GAGG粉体，利用XRD、SEM、荧光光谱仪等对样品表面形貌及发光性能进行表征，研究煅烧温度、沉淀剂引入草酸根对粉体发光性能的影响。结果表明，前驱体经950℃煅烧3 h后全部转变为GAGG相，Pr

、Ce

共掺未改变基质的物相结构；沉淀剂引入草酸铵后，粉体发射光谱积分强度由333 573 a.u上升至420 894 a.u，沉淀剂引入草酸根能提高粉体的发光性能。荧光寿命测试表明，在Ce:GAGG中掺入Pr

可使Ce

的荧光寿命降低，衰减时间为35.43 ns。

Abstract

The Ce

Pr:GAGG powders were prepared by chemical co-precipitation and one step calcinations. The surface morphologies and luminescence properties of the samples were analyzed by XRD

SEM and fluorescence spectrometer. The effects of calcination temperature and the introduction of oxalate into precipitant on the luminescent properties of powders were investigated. The results showed that the precursor transformed into GAGG phase after being calcined at 950℃ for 3 h.The co-doping of Pr

and Ce

did not change the phase structure of the matrix. After the precipitation agent was introduced into ammonium oxalate

the emission spectrum intensity of the powder increased from 333 573 a.u to 420 894 a.u

precipitation agent introduced oxalate can improve powder luminescence performance. The fluorescence lifetime test showed that the incorporation of Pr

in Ce:GAGG can reduce the fluorescence lifetime of Ce

and the decay time is 35.43 ns.
