摘要

选择稀土Eu、Dy、Tm和过渡金属元素Mn，在CaSO

中进行掺杂，制成了CaSO

:RE(Eu

Tm）

Mn和CaSO

:RE

Mn多晶粉末，测量了三种物质的热释光发光谱，研究稀土离子和Mn杂质在CaSO

发光中的相互作用。实验发现：稀土离子与Mn离子既是发光中心，又能对陷阱能级的分布产生影响；Mn

对稀土离子150 ℃以上的高温热释光峰没有增强作用，只对较低温度的发光峰有显著的增强作用，即存在Mn

向稀土离子的能量转移。但Mn

对CaSO

中不同价态的稀土离子的增强作用差异很大，对Eu

的发光有很强的增强作用，对Dy

、Tm

只有较弱的增强。

Abstract

The CaSO

:RE(Eu

Tm）

Mn and CaSO

:RE

Mn phosphors have been prepared by doping the rare earth ions (Eu

Tm) and Mn into CaSO

. The roles of RE and Mn ions dopants and their interactions in the phosphors have been studied by the methods of thermoluminesence (TL) 3D spectra. The results indicated that the dopants not only are luminescence centers

but also influence the distribution of traps. After co-doped with Mn

the higher glow peaks(

150 ℃) of rare earth ions are not intensified

on the contrary

the lower temperature peaks are intensified obviously

and the temperature of peaks are get close to the glow peak of Mn

in CaSO

:RE

Mn phosphors. It is confirmed that the energy transfers from Mn

to the RE ions happened. The experiments also showed that the Mn

will remarkably intensified the luminescence of Eu

but lightly intensified the luminescence of Dy

or Tm

.
