- Аннотация: The refractive indices n of Sr1 - x R (x) F2 + x crystals (R = Y, La-Lu; 0 a parts per thousand currency sign x a parts per thousand currency sign 0.5) have been measured at wavelengths of 0.436, 0.546, and 0.589 mu m. It is established that n increases when there is an increase in the RF3 content x according to a weakly quadratic law for each R. For the isoconcentration series of Sr-0.9 R F-0.1(2.1) crystals, the change in n in the series of rare earth elements has a pronounced nonlinear character, which reflects the nonmonotonous change in the properties of compounds in the R series. It is shown that the method of molecular refraction additivity can be used to calculate n for Sr1 - x R (x) F2 + x crystals. By varying the RF3 content in them, one can obtain optical media with a gradually varied refractive index n in the range 1.44-1.55, thus filling the gap in the n values between high ones for RF3 crystals and low ones for crystals of alkaline earth fluorides MF2.
