摘要：

Li3Ba2Gd3(MoO4)8:Dy3+/Eu3+ phosphors with controllable emission properties were created using a hightemperature solid-phase technique. The phosphors' thermal stability, luminous characteristics, phase purity, and crystal structure were all examined. The noteworthy point is that Li3Ba2Gd3(MoO4)8:Dy3+ phosphors emit red light at 615 nm upon introduction of Eu3+ ions. In order to examine the energy transfer pathway from Dy3+ ions to Eu3+ ions, caused spectrum changes were produced by systematically varying the concentration of Eu3+ ions. Meanwhile, the photoluminescence decay lifespan was measured to verify these results. Moreover, when combined with a commercial LED chip, the device achieved desired to emit warm white light. These findings indicate the potential of Li3Ba2Gd3(MoO4)8:Dy3+/Eu3+ phosphors for application in solid-state lighting.
