TL;DR: In this article, Raman described observations showing that monochromatic light scattered in this manner by crystals is accompanied by radiations of altered wave-length in the same way as in the case of gases and liquids.
Abstract: THE thermal agitation of the atoms in solids results, as was shown by Raman (NATURE, Jan. 12, 1922, and Jan. 6, 1923), in a noticeable blue opalescence in the interior of such transparent crystals as quartz or ice when they are traversed by a strong beam of sunlight. In his address on the discovery of a new type of secondary radiation (Indian Journal of Physics, Mar. 31, 1928) Raman described observations showing that monochromatic light scattered in this manner by crystals is accompanied by radiations of altered wave-length in the same way as in the case of gases and liquids. The difference between the incident and scattered frequencies corresponds, of course, to a characteristic infra-red frequency of the crystal.

TL;DR: The microstructure of CAD-CAM ceramic systems influenced the optical properties and it was showed that other optical properties influence on the natural appearance of dental ceramics.

19 Mar 1934TL;DR: In this article, it was shown that glass compositions in a certain region of the ternary system will separate into two phases, which separation generally is evidenced by the appearance of a slight bluish opalescence in the glass.
Abstract: We have discoverel that glass compositions in a certain region of the ternary systemRO--B203-S102 5 -will, oh the proper heat treatment, separate into two phases, which separation generally is evidenced by the appearance of a slight bluish opalescence in the glass; that one of these phases...

TL;DR: Since the scattering and absorption characteristics influence the color of resin composites, the size and volume fraction of fillers should be controlled for the best color reproduction, considering the refractive indices of filler and resin matrix.
