Light scattering (Raman, Rayleigh and Mandelshtam-Brillouin) and absorption of commercial color glasses (cut-off optical filters containing nanocrystals of ternary compounds CdS_xSe_1–x) were studied. It was found for the first time that the contribution of nanocrystals to the Rayleigh scattering is unprecedentedly low for some of these glasses. This conclusion is confirmed by estimation of nanocrystal size and volume fraction from low-frequency Raman scattering and absorbance spectroscopy for a chosen set of samples. Anomalously low Rayleigh scattering of nanocrystals is explained in terms of interference of light scattered by different nanocrystals (interparticle interference). The possibility of interparticle interference effects in the case of small volume fraction of nanocrystals is illustrated by computer simulation using the model of diffusion-limited phase transformation proposed earlier.

光散射（拉曼，瑞利和曼德尔施坦-布里渊）和商用彩色玻璃的吸收（截止的滤光片，其中包含三元化合物CdS _x Se _{1- x的}纳米晶体））进行了研究。首次发现，对于某些此类玻璃而言，纳米晶体对瑞利散射的贡献是前所未有的低。通过低频拉曼散射和吸收光谱对一组选定的样品估算纳米晶体的尺寸和体积分数，可以证实这一结论。根据不同纳米晶体散射的光的干涉（粒子间干涉）来解释纳米晶体的异常低瑞利散射。使用较早提出的扩散受限相变模型，通过计算机仿真可以说明在纳米晶体的体积分数较小的情况下，颗粒间干扰效应的可能性。
