摘要：

High-quality single crystals of copper metaborate CuB2O4 with a volume exceeding 1 cm(3) are grown. The optical absorption spectra of these crystals are recorded for the first time owing to their sufficiently large size. The spectra exhibit a broad transmission window in the visible region and an intense absorption peak around similar to2.0 eV, which is already split into two bands at room temperature. A weak anisotropy is revealed in unpolarized light upon light beam propagation along the a and c axes. The spectra are compared with the absorption spectrum of CuGeO3 .
