phosphor was synthesized at 900℃ in air by solid-state reaction route. The crystal structure and photoluminescence proerties were characterized by XRD and fluorescence spectra
respectively. The results show that the incorporation of Dy
3+
ions do not change the single-phase structure of SrB

. The PL spectra show the excitation peaks range from 300 to 400 nm is due to the 4f-4f transitions of Dy
3+
. This mercury-free excitation is useful for solid state lighting and light-emitting diodes (LEDs). The emission of Dy
3+
ions upon 349 nm excitation is observed at 484 nm (blue) due to the

which increases rapidly with the increase of Dy

then decreases with increasing Dy
