摘要
本文采用Boltzmann分布近似 ,计算了不同温度下Tm→Ho的净能量转移 ;计算了实验中不同温度下Ho3 + 离子的荧光发射强度在整个Tm—Ho体系荧光发射中的比例。我们的实验和计算表明 ,对Tm—Ho准三能级体系采用Boltzmann分布近似 。
Based on Boltzmann distribution approximation,the net energy transfer from Tm 3+ to Ho 3+ ions has been calculated.The ratio of the emission intensity of Ho 3+ ions to that of the Tm-Ho system at different temperature has also been calculated.Our calculation and experiments showed Boltzmann distribution approximation is valid for the calculation about Tm-Ho quasi three level systems with low pumping intensity.
