摘要

Sm:YAl_3(BO_3)_4 crystal of good optical quality has been grown by the fluxed method. X-ray diffraction experiment show that the crystal has the same structure as that of YAl_3(BO_3)_4 crystal and its unit cell constants have been measured to be a = 9.28954 A, c = 7.24132 A, vol = 541.17 A~3. The thermal properties of Sm:YAl_3(BO_3)_4 crystal have been studied for the first time. The average thermal expansion coefficients are determined to be 2 x 10~(-6)/℃, 9.5 x 10~(-6)/℃ along a- and c-direction. The specific heat of the crystal has been measured to be 0.71 J/g℃ at room temperature.
