摘要

共掺杂离子是优化晶体闪烁性能的重要手段之一，本文采用提拉法生长了GAGG：Ce和GAGG：Ce，0.1% Mg晶体。通过测试硬度、透过率、X射线激发发射（XEL）谱和符合时间分辨率等方法研究了微量MgO掺杂对GAGG：Ce光学及闪烁性能的影响。GAGG：Ce和GAGG：Ce，Mg的维氏硬度平均值分别为1 430 kg/mm

和1 420.4 kg/mm

，表明Mg

的掺杂几乎没有对GAGG：Ce的硬度产生影响。XEL谱结果表明，共掺杂Mg

Abstract

Ions' co-doping is one of the important means to optimize crystals' scintillation properties. In this work

GAGG:Ce and GAGG:Ce

0.1%Mg crystals were grown by Czochralski method. The effects of trace MgO on the optical and scintillation properties of GAGG:Ce were studied by measuring hardness

transmittance

X-ray excited luminescence(XEL) spectrum and time resolution. The average Vickers hardness of GAGG:Ce and GAGG:Ce

Mg is 1 430 kg/mm

and 1 420.4 kg/mm

respectively

which indicates that Mg

doping has little effect on the hardness of GAGG:Ce. Photoluminescence(PL) and XEL spectra show that the emission peak wavelength of GAGG:Ce and GAGG:Ce

Mg crystals is~540 nm. By Gaussian fitting the XEL spectrum

the emission peaks of 5d

and 5d

of GAGG:Ce

Mg are red-shifted 12~24 nm relative to GAGG:Ce

and the introduction of Mg

may change the transition probability distribution of Ce

from 5d

excited state to

5/2

and

7/2

. The light yields of GAGG:Ce and GAGG:Ce

Mg are 5.8×10

lx/MeV(58 000 ph/MeV) and 4.15×10

lx/MeV(41 500 ph/MeV)

respectively

but the coincidence time resolution of GAGG:Ce

Mg is significantly improved

up to 146 ps. In addition

comparing the light yield of samples of different sizes

the self-absorption degree of GAGG:Ce

Mg for scintillation luminescence is less than that of GAGG:Ce. The above results indicate that trace MgO doping is an effective way to improve the scintillation performance of GAGG:Ce crystals.
