The absorption and the luminescence spectra of the new Pr - doped strontium borate Sr4B14O25:Pr3+ crystals were measured. The Sr4B14O25:Pr3+ crystal sample 5?5?9,6 mm3 in size was used for investigation. It was found that the short - wave transparency edge of Sr4B14O25:Pr3+ is 227 nm. The longwave absorption edge of spectra corresponds to 3200 nm The luminescence spectra of the Sr4B14O25:Pr3+ crystal simples were measured by a laser and lamp pump. A strong luminescence line was detected in the orange spectral range ? = 595 nm (1D2 ? 3H4 transition). The polarizing dependence of the luminescence intensity out was determined.
Keywords: luminescence, strontium borate, praseodymium-ion.
