Abstract
Thermal processing of fluorochlorozirconate glasses leads to the formation of BaCl2 nanocrystals within the glass matrix. An alternative method to determine the size of the nanocrystals is provided by a Rayleigh scattering model based analysis of optical transmittance data. For comparison, the size is extracted from X-ray diffraction data with the Scherrer equation. Additional unwanted inclusions of non-crystalline scattering centers lead to significant differences between the results obtained from both of these techniques. Using these two methods allows for a controlled monitoring of nanocrystal growth in optical materials.
