摘要：

In this work, novel phosphors Na5Gd(WO4)(4): Tb3+/Yb3+ and Na5Gd(WO4)(4): Tb3+/Er3+/Yb3+ phosphors were synthesized by the solid state reaction method. The photoluminescence properties were investigated. The introduction of Er3+ to NGW: Tb3+/Yb3+ was used to modify the chromaticity coordinates, then providing a good color tunable property. The change in the chromaticity coordinates induces the shift of emission color from yellow-green to blue-green for NGW: Tb3+/Er3+/Yb3+ as the temperature increases. All the results indicate that the NGW: Er3+/Tb3+/Yb3+ phosphors may be used as optical temperature sensing materials.
