A Study of PbF&sub(2) Nanoparticles Crystallization Mechanism in Mixed Oxyde-Fluoride Glasses / S.Dyussembekova, S.Kichanov, D.Kozlenko, [a.o.] // Ceramics [Electronic resource]. – 2023. – Vol.6, No.3. – P.1508-1516. – URL: https://doi.org/10.3390/ceramics6030093. – Bibliogr.:33.

Samples of nanocrystalline PbF&sub(2) glass ceramics were obtained by heat-treating SiO&sub(2)–GeO&sub(2)–PbO–PbF&sub(2)–CdF&sub(2) glasses. The Ho&sub(2)O&sub(3) and Tm&sub(2)O&sub(3) doping effects on the structural features of PbF&sub(2) nanoparticles were studied using small-angle X-ray scattering and X-ray diffraction methods. The enlargements of the average sizes of nanoparticles and the sizes of local areas of density fluctuations have been found to be correlated with an increase in concentrations of Ho&sub(2)O&sub(3) and Tm&sub(2)O&sub(3) in initial glasses. A variation in the concentrations of Ho&sub(2)O&sub(3) and Tm&sub(2)O&sub(3) does not affect the morphology and fractal dimension of the formed PbF&sub(2) nanoparticles.
