摘要

Transmission spectra of two-component crystals of Sr1-xRxF2+x (R = Y, La-Lu; 0 <= x <= 0.5) in the 1-17-mu m wavelength range were studied. The spectral characteristics of these crystals and of single-component crystals of MF2 (M = Ca, Sr, or Ba) and RF3 (R = La-Nd) were compared. The transmission cutoff of Sr1-xRxF2+x crystals is shifted to shorter wavelengths with increasing x. The same tendency is observed with the increasing atomic number R of rare-earth elements for two isoconcentration series of Sr1-xRxF2+x (x similar to 0.10 and 0.28). This tendency is pronounced at large x. The transmission cutoff of Sr1-xRxF2+x crystals can be varied in the range of from 10.7 to 12.2 mu m by changing their qualitative (R) and quantitative (x) composition. Hence, these crystals can be assigned to multicomponent fluorDEe optical materials with controlled optical characteristics. The Sr1-xRxF2+x crystals, where R = Ce-Sm, were shown to be promising materials for the design of selective optical filters in the 2-10-mu m spectral range.
