Copper metaborate had a unique crystal structure and exhibited noteworthy magnetic phase transitions at 21 and 10 K. The electronic structure and lattice dynamics of copper metaborate Cu<sup>11</sup>B<sub>2</sub>O<sub>4</sub> single crystals were investigated and compared with the optical properties of CuB<sub>2</sub>O<sub>4</sub>, to assess the boron isotope effect. The optical absorption spectrum at room temperature revealed two charge-transfer bands at approximately 4.30 and 5.21 eV with an e ...[more]
