上转换发光材料
测量了这些样品在不同激发光密度下的上转换光发射功率及上转换效率。实验结果表明:在不同激发光密度下
所有样品的光发射功率都存在极大值
其中Yb

和Er
3+
浓度增加
绝对效率的极大值向较低激发光密度方向移动
在Yb

phosphors with different doping concentrations of Yb
3+
Er
3+
were prepared by using the sol-gel method. Up-conversion fluorescence powers and efficiencies were measured under different excitation density. The obtained data show that each sample has a maximum value in emission power. Among those sample
the sample of doping Yb
3+
(4%)
Er
3+
(1%) has the highest power of 20 mW. Each sample had a maximum value of up-conversion absolute fluorescence efficiency. This value shifts to the lower exciting density with the increasing content of Yb
3+
and Er
3+
. The highest efficiency is 3.2% for Yb
3+
(9%) and Er
3+
(3%) sample
and the highest fluorescence efficiency is 6.9%。
