摘要
设计并制备了一种Ｔｍ３＋、Ｙｂ３＋共掺杂的多氟化物调整碲酸盐（ＭＦＴ）玻璃材料，其组份为５０ＴｅＯ２－１４．９ＰｂＦ２－１０ＡＩＦ３－１０ＢａＦ２－１０ＮａＦ－０．１Ｔｍ２Ｏ３－５Ｙｂ２Ｏ３测量了该玻璃系统的Ｒａｍａｎ散射光谱，在９７０ｎｍＬＤ激发下裸眼可以观察到很强的蓝色荧光，光谱测量证实这个蓝色发射（４７６ｎｍ）来源于１Ｇ４→３Ｈ６的跃迁，同时，还有两个较弱的红色发射源于１Ｇ４→３Ｈ４和３Ｆ４→３Ｈ６跃迁．测量并讨论了蓝色、红色上转换荧光强度与ＬＤ工作电流的关系．这个关系表明蓝色上转换发射需要三个光子参与，而红色（６６３ｎｍ）发射需要两个光子参与实现．
In this paper, fabrications of GeO 2 PbF 2 WO 3 Tm 2O 3 glasses were studied. The Raman spectra of different samples have been measured. In this system an efficient pumped wavelength for upconversion emission was confirmed, and their upconversion emissions by 650nm pumped by 650nm were observed at room temperature.
