Uniform upconversion in erbium-doped silicate glasses is investigated as a function of glass composition, concentration, and fabrication method. Comparisons of upconversion coefficients are made among soda lime silicate and aluminosilicate bulk glasses and soda lime silicate waveguides. Comparisons are also made with studies performed by other researchers. The results indicate that both the composition and the preparation method of the glass affect the value of the upconversion coefficient, with as much as a factor-of-4 variation observed at fixed Er(3+) concentration. Values of the upconversion coefficient are found to be consistent with the Förster-Dexter microscopic model.
研究了掺铒硅酸盐玻璃中的均匀上转换作为玻璃成分、浓度和制备方法的函数。比较了钠钙硅酸盐和铝硅酸盐块状玻璃以及钠钙硅酸盐波导中的上转换系数。还与其他研究人员进行的研究进行了比较。结果表明,玻璃的成分和制备方法都会影响上转换系数的值,在固定的Er(3+)浓度下观察到高达4倍的变化。发现上转换系数的值与Förster-Dexter微观模型一致。
