- •
MY2−x(MoO4)4:xSm3+ (M=Ca, Sr and Ba) were prepared by a solid-state reaction method.
- •
The optimum Sm3+concentration for Sr system is 0.3, while is 0.5 for both Ca and Ba.
- •
Emission intensity of SrY2(MoO4)4:Sm3+ is the strongest among Ca, Sr and Ba systems.
- •
Energy transfer process from Sm3+ to Eu3+ in phosphors were investigated in detail.
- •
When co-doped Eu3+ amount is 0.9, three systems have the highest emission intensity.
