在商用 980 nm 激光二极管的激发下，Tm3+∕Yb3+ 共掺杂没食子酸铋铅玻璃中实现了强烈的蓝色上转换。能量转移过程和激发态吸收解释了 Tm3+ 的 G41 发射能级的数量。虽然GeO2的添加增强了玻璃的热稳定性，但与GeO2振动相关的声子模式对蓝色上转换强度和H43能级的辐射寿命几乎没有影响。已经讨论了主体的声子能量对多声子衰变对荧光的贡献的依赖性。在掺入 PbF2 含量的没食子酸铋铅玻璃中也观察到蓝色上转换的显着增强。在商用 980nm 激光二极管的激发下，Tm3+∕Yb3+ 共掺杂没食子酸铋铅玻璃中实现了强烈的蓝色上转换。能量转移过程和激发态吸收解释了 Tm3+ 的 G41 发射能级的数量。虽然GeO2的添加增强了玻璃的热稳定性，但与GeO2振动相关的声子模式对蓝色上转换强度和H43能级的辐射寿命几乎没有影响。已经讨论了主体的声子能量对多声子衰变对荧光的贡献的依赖性。在掺入 PbF2 的没食子酸盐-铋-铅玻璃中也观察到蓝色上转换的显着增强。
Intense blue-upconversion in Tm3+∕Yb3+-codoped gallate–bismuth–lead glasses has been achieved under an excitation from a commercially available 980nm laser diode. Energy transfer processes and excited-state absorption account for the population of the G41 emitting level of the Tm3+. Although the addition of GeO2 has enhanced the glass thermal stability, the phonon mode associated with vibration of GeO2 has almost no influence on the blue-upconversion intensity and the radiative lifetime of H43 level. The dependence of the phonon energy of the host on contributions from multiphonon decay on the fluorescence has been discussed. Significant enhancement of the blue-upconversion has also been observed in gallate–bismuth–lead glasses with the incorporation of PbF2 content.Intense blue-upconversion in Tm3+∕Yb3+-codoped gallate–bismuth–lead glasses has been achieved under an excitation from a commercially available 980nm laser diode.
