## Abstract Recently, a strong cathodoluminescence at 215 nm (photon energy 5.765 eV) has been reported on pure HPHT hexagonal boron nitride (hBN) single crystals (K. Watanabe et al., Nature Mater. **3**, 404 (2004)). For the first time, we measured the photocurrent and optical absorption spectra o
