“…The grain size varies from 5-7 to 25-30 μm. ions in ZnO crystals [74][75][76], and the absorption band at longer wavelengths (𝜆 > 1800 nm) which is connected with the presence of free carriers in semiconductor ZnO crystals [80], see Fig. 22(a).…”

“…8(c). In literature, information about the reflectance spectrum of Ni 2+ : Zn2SiO4, αwillemite, is evaluable [80]. The spectrum exhibits a wide, intense band in the range of 480-760 nm with absorption maxima at 540, 584, and 633 nm, which corresponds to 3 T1(F) → 3 T1(P) d-d transition in the tetrahedral environment.…”

“…First, ZnO nanocrystals cause a significant scattering of visible light. Second, the absorption band at long wavelengths (𝜆 > 1000 nm) was observed which is related to the presence of free carriers in semiconductor ZnO nanocrystals [80] and is generally discussed in terms of localized surface plasmon resonance (LSPR). Finally, a fine effect of the changes in intensities and positions of Er 3+ and Yb 3+ absorption peaks was demonstrated for the first time using the analysis of difference of optical densities (Eq.…”

“…To our knowledge, the third method of exclusion of reflection losses from the measured optical density was first proposed in Ref. [ 36 ] (see Equation (3) of this reference). The method allowed us to observe the small changes in the shape of Er 3+ ion absorption peaks and the appearance of light scattering due to the precipitation of ZnO nanocrystals, and to determine the values of the scattering exponent.…”

A Simple Method for Estimation of the Scattering Exponent of Nanostructured Glasses

For most of nanostructured glasses (NGs) (phase-separated glasses and glass-ceramics), the light scattering coefficient (turbidity) is described by a power function of the inverse wavelength with an exponent which differs appreciably from the Rayleigh value 4 and is called the scattering exponent. The knowledge of the scattering exponent of a material is important from both fundamental and practical points of view. Previously, we developed three rather complex methods to determine the scattering exponent. Here, we present a novel simple express method for its estimation. In the method, the measured optical density for only one sample is used, the refractive index of the material is not required, and the dispersion of refractive index is assumed to be insignificant. The method is based on the differentiation of the measured optical density with respect to the wavelength. The scattering exponent values obtained by the new method for NGs of different types are in good agreement with those found by the traditional methods. The new method is found to be applicable even to NGs with high dispersion of refractive index. Thus, the new method does not require the data on the refractive index dispersion and can be applied without restrictions.
