摘要：

Increasing the absorption capacity of trivalent rare-earth metal ions doped phosphors excited by ultraviolet (UV) light is a hot topic. Herein, a novel beta-Ba2ScAlO5:Eu3+ red-emitting phosphor with strong absorption in the UV region was reported. The photoluminescence spectra show that beta-Ba2ScAlO5:Eu3+ phosphor exhibited a broad charge transfer band ranging from 220 nm to 350 nm, and it can transfer the excited electrons to Eu3+ ions. A strong red emission peak of Eu3+ ions centered at 613 nm (D-5(0) -> F-7(2) transition) was observed under 300 nm excitation. The Judd-Ofelt intensity parameters Omega(2) and Omega(4) were calculated as 1.37 x 10(-2)0 cm(-2) and 0.14 x 10(-2)0 cm(-2), which indicates a higher asymmetry environment around Eu3+ ions. All experimental results suggest that beta-Ba2ScAlO5: Eu3+ materials as red phosphors own potential for application in light-emitting diodes and optical temperature sensors.
