Abstract
The codoping of a heavy-metal fluoride glass by two rare-earth ions, erbium and ytterbium, permits the semiconductor laser infrared excitation of two visible neighboring fluorescence lines of erbium by upconversion, the intensity ratio of which is a single variable function of temperature.
摘要
通过铒和镱这两种稀土离子对重金属氟化物玻璃进行共掺杂，可实现半导体激光对铒的两条相邻可见荧光线进行红外激发上转换，这两条荧光线的强度比是温度的单变量函数。
