摘　要:稀土摻雜氧氟玻璃是一種優良的上轉換發光材料，制備了組分為35SiO2—15AlO1.5-（45-x）PbF2-xCdF2—0．1TmF3—1．5YbF3（x=0，10，20，30）的氧氟硅酸鹽玻璃，系統研究了CdF2含量對其熱學性能和光學性能的影響。研究表明用CdF2部分替代PbF，可以提高玻璃的熱穩定性、使紫外吸收截至邊向短波方向移動；隨著CdF2含量的增加，開始Tm^3＋藍光和紅光上轉換發光增強緩慢，而后迅速增強．而近紅外上轉換發射先顯著增強后增強放緩；由于藍光和近紅外發光強度遠大于紅光發光強度，所以該氧氟玻璃更適合于藍光和近紅外發光材料。最后，探討了Tm^3＋的上轉換發光機理。[

 Abstract:Tm^3＋-Yb^3＋ codoped oxyfluoride silicate glasses suitable for upconversion laser were fabricated and the effect of CdF2 addition on thermal stability and upconversion luminescence properties in it were systematically investigated. The experimental results indicate that, with the substitution CdF2 for PbF2, the glass thermal stability increases and the UV cutoff edge moves to short-wave band slightly. With increasing CdF2 content, the blue and red upconversion luminescence intensity increase slightly at first, and then increase rapidly. While the near infrared （NIR） upconversion emission intensity increases notably at first and then increases slightly. However the blue and NIR luminescence intensity are much stronger than that of red, indicating these oxyfluoride silicate glasses are more preferable for blue and NIR emissions than red emission. The possible upconversion mechanisms for the blue, red and NIR fluorescence are also estimated and evaluated.[著者文摘]/。
