通过测量Nd/Cr：YAG（Nd：1.0%，Cr：2.0%）材料的荧光特性随温度的变化，研究了Cr ~（3+）向Nd ~（3+）的能量传递。Nd ~（3+）的荧光强度随温度的升高而增强，这是由于Cr ~（3+）的吸收系数增大所致。在77 ~ 450 K温度范围内，能量传递效率基本不变。能量传递时间随温度的升高而缩短。
The energy transfer from Cr3+to Nd3+for Nd/Cr:YAG (Nd: 1.0%, Cr: 2.0%) materials was investigated by measuring the temperature dependences of fluorescence characteristics. The fluorescence intensity of Nd3+increased with temperature owing to enhancement of the absorption coefficient of Cr3+. The energy transfer efficiency was constant from 77 to 450 K. The energy transfer time decreased with increasing temperature.
