Abstract
The wavelength dependence of the light extinction coefficient in -doped glass-ceramics containing nanocrystals is studied experimentally. In a wide spectral range, this dependence is described by the power law with the constant exponent () and is attributed to light scattering. The samples containing nanocrystals demonstrate the values of that are appreciably greater than 4. This phenomenon known as anomalous light scattering in nanostructured glasses contradicts the generally accepted opinion that for glass-ceramics. The present study enlarges the group of nanostructured glasses exhibiting anomalous light scattering.
