Abstract
Optical investigations of crystals of solid solutions NdxGd1 – xCr3(BO3)4, 0.01 ≤ x ≤ 1, have been performed. Absorption spectra in the range of wavenumbers 11 000–15 000 cm–1 recorded at cryogenic temperatures (16 K) reveal a significant effect of the concentration of Nd3+ ions in the structure on the absorption in the near infrared range of the spectrum due to f–f transitions in the Nd3+ ion. It has been found that, at a concentration of х > 0.6, two nonequivalent Nd3+ centers are observed in the absorption spectra, which is explained by the presence of two polytypic modifications.
