“…Thus the scattering of light in G1 glass has an anomalous character. This conclusion qualitatively agrees with that concerning the presence of ordering elements in the relative position of the scattering particles in G1 glass, 18 and this must involve anomalous light scattering. 11,12 A quantitative interpretation of the ελ dependence for G1 glass is not currently possible, since this would require data on the structure factor of the system of particles in G1 glass, which do not appear in the literature.…”

“…Since there are no data on the presence of inhomogeneities in G0 glass, it is not possible to discuss the extinction behavior. Glass G1, which contains spherical particles having a mean radius of 20.7 nm and volume fraction 0.047, 18 scatters light a factor of 4-5 more strongly than the initial G0 glass. The extinction coefficient of G1 glass is ε ≈ 0.08 cm −1 at λ 400 nm and decreases with increasing wavelength to a value of ε ≈ 0.019 cm −1 at λ 550 nm.…”

This paper is devoted to the study of light scattering in inhomogeneous glasses. The spectral behavior of the extinction coefficient of the initial sodium borosilicate glass and two glasses obtained by heat treatment is experimentally studied. It is established that the extinction coefficient of heat-treated glasses in the visible region is determined by the scattering of light. Experimental data on the anomalous spectral dependence of the extinction coefficient of the glass subjected to more prolonged heat treatment are compared with the results of calculations carried out in terms of various scattering models based on literature data on the structure of this glass, which consists of liquation spherical particles in a matrix. It is shown that the ordering effects observed earlier in the relative position of the particles play an important role in the light scattering. It is pointed out that, to theoretically describe the scattering properties of a system of polydisperse particles, it is necessary to know the pairwise correlation function of the particles, which depends on the size of the particles in the pair.

“…The size of the inhomogeneous regions reported here was calculated by approximation of scattering by a monomodal system of spherical particles with constant density over the volume, either by the Guinier method from the slope of the plot of lnI versus φ 2 , or from the location of the maximum of the plot φI(φ) versus φ. It should be pointed out that in the case of interference effects due to the regularity in the distribution of scattering regions [82,83], the calculated sizes could be estimated excessively high when using the first or set too low when using the second method. In our case, the coherent scattering effects gave the difference which did not exceed 2-3%.…”
