A series of novel Dy 3+  activated aluminate Ba 2 Y 1- x  Dy x AlO 5  ( x  = 0.01–0.30) red-emitting phosphors were synthesized through a high-temperature solid-state route at 1380°C. The X-ray diffraction patterns revealed that the samples were well crystallized in the space group  P 2 1/c  (No. 14). The spectrum analysis revealed that under UV light excitation, Ba 2 YAlO 5 :Dy 3+  phosphor exhibited blue and yellow peaks corresponding to  4 F 9/2 – 6 H 15/2  transition and  4 F 9/2 – 6 H 13/2  transition, respectively. The optimum dopant concentration of Dy 3+  ions is around 2 mol% and the critical transfer distance of Dy 3+  is calculated as 29 Å. The concentration quenching mechanism between Dy 3+  has been investigated. Results indicate that Ba 2 YAlO 5 :Dy 3+  offers the excellent optical properties as a potential yellow-emitting phosphor candidate for n-UV LEDs.
