稀土发光中心能级的热移位(Ⅰ)

Themal Shift of Energy Levels in the Rare Earth Luminescence Centers --Ⅰ. In the YAG: Nd^(3+)

在10—550K的温度范围内首次系统地研究了YAG:Nd^(3+)的斯塔克能级R_1和R_2的热移位。

The Stark energy levels R1 and R2 of the absorption spectrum of YAG: Nd3+ have measured in the temperature range 10-550K. The thermal shift of these energy levels were observed. A theoretical calculation for these wave length thermal shifts have been worked out with a modified equation and the theoretical results are in accordance with those experiments.
