Temperature behavior of thermal expansion and birefringence of In (x) Tl1-N... D dagger-substitution solid solutions

摘要

Results of studying the optical properties of In (x) Tl1-N... I solid solutions in the concentration domain of 0.4 ae N... ae 0.9 are presented. The dependence of relative linear expansion of In (x) Tl1-N... I crystals (D cent = 300-520 K) has been obtained. In (x) Tl1-N... I crystals (D cent = 300-520 K). Based on this, the temperature dependence of thermal-expansion coefficient alpha has been found. Dependence of birefringence Delta n (i) on temperature and concentration of the TlI component in the solid solution has been studied.
