摘要 用速率方程方法研究了Er:YAG的红外荧光和上转换荧光的激发光谱 ,理论分析和计算结果表明 ,在实验中观察到的线性荧光激发光谱中的烧孔现象 ,是上转换荧光和线性荧光相互竞争的结果。 Infrared and upconversion fluorescence excitation spectroscopy of Er 3+ :YAG is studied using rate equation method. Theory analysis and calculation indicate that the hole_burned in the linear fluorescence excitation spectroscopy is resulted from the competition between the infrared fluorescence and upconversion.
