中文摘要：

对稀土离子能级的动力学过程进行了数值计算,并对各个能级的布居概率改变进行了分析。发现如果不考虑斯托克斯过程和反斯托克斯过程之间的区别而采用原有声子辅助能量传递理论中相同的计算公式对待两种过程的话,得到的理论计算结果就与我们实验得到的校准的结果不一致,为了能够准确描述反斯托克斯能量传递过程,众所周知的量子喇曼理论相对于经典拉曼理论在斯托克斯与反斯托克斯过程的强度比上所增加的比值系数exp{ΔE/kT}被首次成功地引入来描述反斯托克斯能量传递。在能量传递计算理论中引入该比值系数之后,理论计算结果与实验结果符合的非常好,并且发现该比值系数在对纳米尺度材料的光子学研究探索中会发挥至关重要的作用。

英文摘要：

The dynamics of all levels were calculated numerically in the present article for Er（0.5）Yb（3）：FOV oxyfluoride nanophase vitroceramics.The population dynamical processes were analyzed carefully.It was found for the first time that traditional phonon-assisted energy transfer theory of rare earth ion energy transfer can not well explain the observed experimental calibrated results,as it does not take into account the difference between Stokes and anti-Stokes process.A coefficient,the improved factor of the intensity ratio of Stokes to anti-Stokes process in quantum Raman theory compared to classical Raman theory,was introduced for the first time to successfully describe the anti-Stokes energy transfer.The theoretical improvement results are coincident with experiments very well.This improvement is very significant and indispensable when the photonics of nano-materials is probed.
