Improved luminescence of Y2MoO6:Eu3+ by doping Li+ ions for light-emitting diode applications

► Incorporated with Li+ ions, the luminescence intensity of Y2MoO6:Eu3+ is enhanced greatly. ► The excitation band of Y2MoO6:Eu3+ covered from 250 to 450 nm. ► Incorporated with Li+ ions into Y2MoO6:Eu3+, the 4f-4f transition of Eu3+ at 465 and 530 nm is increased significantly.
