Synthesis and two-color emission properties of BaGd2(MoO4)4:Eu3+,Er3+,Yb3+ phosphors

► Novel two-color emission phosphor BaGd2(MoO4)4:Eu3+,Er3+,Yb3+ is obtained. ► Upconversion visible emissions are produced through multiple process including ground-state absorption and energy transfer. ► Under UV excitations, the red emission is contributed to the transition emission of Eu3+ (5D0 → 7F1 and 5D0 → 7F2).
