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 l = 595 nm (1D2 ? 3H4 transition). The
polarizing dependence of the luminescence intensity out was
determined.
