摘要：选择若干玻璃组成 ,制得了含莫来石晶相的透明微晶玻璃 ,利用吸收光谱和室温荧光光谱对玻璃和微晶玻璃的发光进行了研究。研究表明 ,在一定温度范围内提高玻璃的晶化温度可以提高Cr3 +离子的有效发光效率 ;Cr3 +离子浓度的增加使微晶玻璃的发光强度增加 ,但引起浓度淬灭 ,降低Cr3 +离子的有效发光效率。对微晶玻璃荧光光谱中 6 88nm发射肩的成因进行了探讨 ,提出了微晶玻璃荧光光谱中 6 88nm和 70 0nm发射可能由2 E能级分裂引起的观点。
By selecting some glass cimpositions the transparent glass-ceramics containing mullite crystal phase are obtained. The luminescent behaviors of these glasses and glass-ceramics were investigated according to the absorption spectrum and fluorescence spectrum. The results indicate that the emission intensity of glass-ceramic will enhance when the crystallization temperature was increased in limited range, as a result the effective luminescent efficiency of Cr3+ ion will increase. The increase of Cr3+ ion concentration will cause the increase of emission intensity of glass-ceramics, but it will cause concentration quenching and decrease the effective luminescent efficiency of Cr3+ ion. The origin of 688 nm emission shoulder in the glass-ceramic fluorescence fluorescence spectrum is discussed, and it is suggested that the 700 nm and 688 nm emission should be attributed to the split of 2E energy level.
