介绍了莫来石陶瓷中Cr的详细光谱研究。吸收和发射光谱的巨大展宽，高度非指数发光衰减和发光线变窄表明这种材料具有很大的固有不均匀性。本文试图通过引入可用于Cr的站点的统计分布来定量描述这种效应。实验结果得到了相当好的再现。
Detailed spectroscopic studies of Cr in mullite ceramics are presented. An enormous broadening of absorption and emission spectra, highly nonexponential luminescence decays and luminescence line narrowing suggest a large inherent inhomogeneity of this material. An attempt is presented to quantitatively describe this effect by introducing statistical distribution of sites available for Cr. A reasonably good reproduction of experimental results is achieved.
