研究了碱土金属氧化物对Bi离子掺杂RO-Al2O3-SiO2 (R=Ca, Sr, Ba)玻璃近红外超宽带发光性质的影响. 结果表明: 玻璃样品在不同抽运源激发下都可检测到较强的近红外超宽带发光. 在808 nm激光激发下, 随着碱土金属离子半径的增加, Bi离子在1 300 nm附近的近红外发光强度显著增加, 荧光半高宽逐渐增加, 其荧光寿命最长可超过600 ms; 而在690 nm激光激发下, 随着碱土金属离子半径的增加, Bi离子在1 100 nm附近的近红外发光呈减弱趋势, 荧光半高宽逐渐增大, 半高宽最大可超过400 nm. 近红外发光可能源于两种不同形式铋的发光中心. 针对上述结果探讨了该玻璃体系中Bi离子近红外发光的机理.

Influences of alkaline earth oxides on super broadband near infrared luminescence properties from Bi-doped RO-Al2O3-SiO2 (R=Ca, Sr, Ba) aluminosilicate glasses are investigated. The results show that under different pumping sources, the near infrared (NIR) luminescence shows different behaviors. Under 808 nm excitation, the infrared emission located at 1300 nm with lifetime more than 600 ms is observed, whose intensity increases with the increase of ionic radius. However, under 690 nm excitation, the luminescence at 1100 nm with a full width at half maximum of 400 nm decreases with the increase of ionic radius. According to the above results, it is suggested that infrared emissions may originate from Bi+ and BiO.-
