Crystal Growth and Characterization of Sr$_{3}$ Y(BO $_{3}$) $_{3}$

The growth, optical and luminescence characteristics of Pr-doped Sr
₃
Y(BO
₃
)
₃
(Pr:SrYBO) single crystals are studied. The Pr:SYBO single crystals with dimension of φ 2.0 × 30 mm
³
were grown by micro-pulling down method with radio frequency heating system. The emission bands at 280-300 nm and 608 nm correspond to 5d-4f transition and 4f-4f transition of Pr
³⁺
respectively, and were observed under 250 nm excitation. Under the α-ray excitation only the 4f-4f luminescence of Pr
³⁺
was observed.
