Abstract

Spectral distribution of photoluminescence (PL) of Li2B4O7:Cu single crystals in unpolarized and polarized light is studied depending on their crystallographic orientation. A complex structure of the main PL peak is detected. The sample orientation is shown to produce no effect on the positions of the spectral maxima in unpolarized light. In polarized light, a redistribution of intensities of components of the main PL peak is observed depending on the sample orientation.
