结构自还原效应对铋掺碱土金属硅磷铝硼玻璃超宽带近红外发光的影响*
Effects of sefl-reduction of glass matrix on the broadband near infrared emissions from Bi-doped alkali earth aluminoborosilicate glasses*
摘要
Abstract
We report the effects of self-reduction of glass matrix on the broadband near infrared (NIR) emissions from Bi-doped alkali earth aluminoborosilicate glasses. Bi2O3-doped as well as Eu2O3,-doped as a comparison, 35SiO2-25AlPO4-12.5Al2O3-12.5B2O3-15RO (R=Ca,Sr,Ba) glasses were prepared in air. Results show that the self-reduction process of Eu3+→Eu2+occurs in this glass matrix. Meanwhile the intensity of NIR emission peaked at about 1300 nm increases with the increase in the radius of alkali earth ions, while the intensity of both NIR emission peaked at about 1100 nm and the red emission from Bi2+decreases. Then the origins of infrared-emitting bismuth centers were discussed according to the correlation of the conversion of Bi ions with the size of alkali earth ions. The results of this work is helpful for understanding the nature of Bi-NIR-emission and may be a guide for the selection of composition of high performance Bi-doped glass.关键词
