摘要：
Several weak absorption bands have been observed in the optical absorption spectra of pure and rare-earth-doped YAl3(BO3)(4) single crystals in the 3350- 3650 cm(-1) wave number region. Two of them, peaking at about 3377 cm(-1) and 3580 cm(-1) in the 8 K spectra, appear in most of the samples. They are tentatively attributed to the stretching mode of OH- ions incorporated in the crystal during the growth. An additional absorption band at about 5250 cm(-1) at 8 K has also been detected in almost all samples. The temperature and polarization dependences of these bands, and their possible origin, are discussed.
