The optical absorption spectra of Li6Y(BO3)3:Er3+ crystals have been studied. The absorption lines corresponding to intraconfiguration electronic transitions from the 4I15/2 ground state to the levels of excited states of Er3+ ions have been found in the spectral range of 370-700 nm. The transitions to the 4F9/2, 4S3/2, 2H11/2, 4F7/2, 4F5/2, 4F3/2, 2H9/2, and 4G11/2 levels have been investigated in detail at 2 K. The number of lines observed for these transitions corresponds to the theoretical maximum for the f-f electronic transitions in Er3+ ions located in the noncubic crystal field. The narrowness of the lines observed and their number indicate that erbium occupies one regular position (specifically, the yttrium position). The energy levels of the excited states have been determined for the transitions under study.
