Abstract

Absorption spectra of Pr3+ and Dy3+ embedded in three glass matrices (SiO2-P2O5-GeO2, Al2O3-B2O3-SiO2 and LiB3O5) have been studied in detail in the near infrared spectral range. The temperature related behavior of the intensity, width and position of the observed absorption lines were studied. It has been shown that f-f transitions in the studied glasses are mainly allowed by static odd distortions of the ligand environment, and these distortions decrease with a rise in temperature. Comparative analysis of the parameters of the absorption lines and their temperature dependencies in different materials have enabled us to ascertain the difference of size, symmetry and dispersion of distortions of the nearest environment of these rare earth ions in different glasses.
