摘要

Crystals of the Sr_(1 - x) Ce _x F_(2 + x) compositions close to the congruent one (x ～ 0.3) are fabricated by the vertical directional crystallization. It is shown that the use of CF_4 to form a fluorinating atmosphere during growth leads to additional spurious absorption in the crystals in the range 350-600 nm. The use of PbF_2 and ZnF_2 for fluorination makes it possible to obtain colorless Sr_(1 - x) Ce _x F_(2 + x) crystals of the desired optical quality from melt. The thermal conductivity of crystal with x ～ 0.28 in the temperature range 80-500 K lies within 1.50 ± 0.03 W m ~(-1) K~(-1). High ionic conductivity makes the Sr _(1 - x) Ce _x F_(2 + x) crystals promising for application in solid-state ionics.
