摘要
研究了掺Ｃｒ３＋透明莫来石微晶玻璃的吸收光谱及荧光光谱，计算了未晶化玻璃和微晶玻璃的晶体场参数。未晶化玻璃与微晶玻璃的晶场强度Ｄｑ值分别为１６００ｃｍ－１和１７２４ｃｍ－１。微晶玻璃的荧光光谱与绿宝石相似，为锐线和宽带并存。
he absorption spectra and fluorescence spectra of Cr^3+ doped transparent mullite glass ceramic were studied. The crystal field parameters of mother glass and glass ceramic were also calculated. The value of Dq of glass and glass ceramic are 1600cm-1 and 1724 cm-1 respectively. The crystal field strength of glass ceramic nears to that of alexandrite(BeAl_2O_4:Cr^3+), and broad emission and sharp emission coexist in the fluorescence spectra.
