含Nb_2O_5和La_2O_3系统玻璃形成区

FORMATION RANGES OF GLASS CONTAINING Nb_2O_5 AND La_2O_3

用新的玻璃形成区探索方法研究了Ｌａ２Ｏ３ 的质量分数分别为１％ ，５％ ，１０％ 时含Ｎｂ２Ｏ５ ，Ｌａ２Ｏ３ 系统玻璃的形成区（ 玻璃生成体分别为Ｐ２Ｏ５ ，ＳｉＯ２ ，Ｂ２Ｏ３，ＴｅＯ２ ＋ ＧｅＯ２ ，修饰体为ＢａＯ，ＺｎＯ） ． 这些系统可作为激光激活离子Ｎｄ３ ＋ ，Ｙｂ３＋ ，Ｈｏ３＋ ，Ｔｍ３ ＋ ，Ｅｒ３＋ 等掺杂的理想基质．

Formation ranges of glass containing Nb 2O 5 and La 2O 3 were studied by new method for exploration of glass formation in new systems when La 2O 3 is 1%,5%,10% (in mole) and glass former are P 2O 5,SiO 2,B 2O 3 and TeO 2+GeO 2 respectively (modifer is BaO and ZnO respectively). These systems of glass may be taken as excellent hosts for doping of lasing ions such as Nd 3+ ,Yb 3+ ,Ho 3+ ,Tm 3+ and Er 3+ .
