Abstract:

采用不同波长的红色脉冲光,激发镶嵌有LaF3Tm3+纳米晶体颗粒的透明氟氧化物玻璃陶瓷样品,测量了不同环境温度下样品的荧光发射谱,记录了荧光发射强度随环境温度的变化规律.实验结果显示,在643.2nm脉冲光激发下,上转换454nm在100~200K的温度范围内有很强的荧光发射,并且荧光强度随着环境温度的降低先增强而后减弱;当采用656.0和638.0nm脉冲光激发样品时,上转换荧光发射强度随环境温度的降低而逐渐增强,其中643.2和638.0nm脉冲光激发下的上转换效率高于656.0nm激发时的结果,表明波长接近于激发态吸收的激发光泵浦样品时,更容易实现Tm3+的频率上转换.最后,从基质声子分布特点等方面对实验结果给出了合理的解释.
