摘要：

对于介质中的发射体，不同的宏观或微观理论模型预测自发发射寿命对折射率的显著不同的依赖性。对Eu $^{3+}$、Ce $^{3+}$和Nd $^{3+}$离子以及不同介质中的量子点进行了各种测量。用不同的模型解释了自发发射率与折射率的关系。通过仔细检查一些实验结果，我们注意到，一些解释是基于隐含的假设，这是很难证明，和一些测量包含太大的不确定性，区分不同的模型。在这项工作中，我们重新分析了现有的测量结果，并给出了一致的解释。

英文摘要：

For emitters in a medium, different macroscopic or microscopic theoretical models predict substantially different dependencies of the spontaneous emission lifetime on refractive index. Various measurements have been carried out on Eu$^{3+}$, Ce$^{3+}$ and Nd$^{3+}$ ions, and quantum dots in different surrounding medial. The dependence of the spontaneous emission rates on refractive index has been interpreted with different models. By closely examining some of the experimental results, we notice that some interpretations are based on implicit assumptions which are hard to justify, and some measurements contain too big uncertainties to discriminate among different models. In this work we reanalyse the avilable measured results and give a consistent interpretation.
