In this paper, the Sr 3 Y 2 (BO 3 ) 4 : Eu 3+ phosphor was synthesized by high temperature solid-state reaction method and the luminescence characteristics were investigated. The emission spectrum exhibits one strong red emission at 613 nm corresponding to the electric dipole 5 D 0 – 7 F 2 transition of Eu 3+ under 365 nm excitation, this is because Eu 3+ substituted for Y 3+ occupied the non-centrosymmetric position in the crystal structure of Sr 3 Y 2 (BO 3 ) 4 . The excitation spectrum indicates that the phosphor can be effectively excited by ultraviolet (254 nm, 365 nm and 400 nm) and blue (470 nm) light. The effect of Eu 3+ concentration on the red emission of Sr 3 Y 2 (BO 3 ) 4 : Eu 3+ was measured, the result shows that the emission intensities increase with increasing Eu 3+ concentration, then decrease. The Commission Internationale del’Eclairage chromaticity (x, y) of Sr 3 Y 2 (BO 3 ) 4 : Eu 3+ phosphor is (0.640, 0.355) at 15 mol% Eu 3+ .
