摘要

研究了Yb

/Er

共掺杂和Ce

/Yb

/Er

三掺杂及其随着Al(PO

)

含量改变的氟磷玻璃的光谱性能。从能量匹配及能级结构角度出发分析了Ce

和Al(PO

)

对其光谱性能的影响。结果表明:在Yb

/Er

比为4 ∶ 1不变而同步增加其含量时

其上转换发光出现了由绿光到黄光再到红光的变化;随着玻璃中Ce

的引入

产生了Er

的

11/2

13/2

能级间无辐射弛豫速率增加现象

且上转换发光都有一定程度的减弱。随着Al(PO

)

含量的改变

其减弱程度也发生相应的改变。同时

通过对其上转换机理的分析得出了红、绿、蓝发光的光子过程。

Abstract

Optical properties of Yb

/Er

co-doped

/Yb

/Er

co-doped fluoride phosphate glass and that of Ce

/Yb

/Er

co-doped fluoride phosphate glass with different content of Al(PO

)

were stu-died. Based on up-conversion mechanism

energy matching and level

the effect of content of Ce

and Al(PO

)

on the optical properties have been analyzed. The results show that the light changes from green to yellow then to red with the content of Yb

/Er

increasing and keeping the ratio of Yb

/Er

as 4 ∶ 1. And with the introduction of Ce

into the glass

non-radiative relaxation takes place from the

11/2

13/2

level of Er

which weakens the up-conversion of light to some extent. Phonon energy of energy transfer process of Er

and Ce

change with changing content of Al(PO)

and the degree of extinction also changes correspondingly. At the same time

through the mechanism of their up-conversion

we get the photon conversion process of red

green and blue light.
