Novel color-adjustable phosphors Sr₈MgCe(PO₄)₇:Tb³⁺ were synthesized by the solid-state reaction method. The X-ray diffraction was used to characterize the phase formation. The host shows blue emission under 310 nm excitation, ascribed to the 5d-4f transitions of Ce³⁺, while Sr₈MgCe(PO₄)₇:xTb³⁺ phosphors exhibit the emission band of Ce³⁺ as well as the characteristic lines of Tb³⁺ under 310 nm excitation. The color variation was observed as the concentration of Tb³⁺ changes. Moreover, the host sensitizes the emission of Tb³⁺ through the energy transfer process, and the mechanism is the dipole–dipole interaction. In addition, the emission of the host declines with the increase of the temperature while that of Tb³⁺ increases. This anti-thermal quenching behavior was interpreted by the configurational coordinate diagram. In addition, the temperature sensing behavior based on the emission peaks of the host and Tb was studied in the range 298–523 K, and the largest sensitivity is 0.379% K⁻¹. The results indicate that Sr₈MgCe(PO₄)₇:Tb³⁺ is an attractive color-tunable phosphor for solid state lighting and temperature sensing.

通过固相反应法合成了新型的颜色可调荧光粉Sr ₈ MgCe（PO ₄）₇：Tb ³⁺。X射线衍射用于表征相形成。主体在310 nm激发下显示蓝色发射，归因于Ce ³⁺的5d-4f跃迁，而Sr ₈ MgCe（PO ₄）₇：x Tb ³⁺磷光体显示Ce ³⁺的发射带及其特性310 nm激发下的Tb ³⁺谱线。随着Tb ³⁺的浓度观察到颜色变化变化。此外，主体通过能量转移过程使Tb ³⁺的发射增敏，其机理是偶极-偶极相互作用。另外，主体的发射随着温度的升高而下降，而Tb ³⁺的发射则随着温度的升高而下降。这种抗热淬火行为由构型坐标图解释。此外，基于主体和Tb的发射峰的温度感测行为在298–523 K范围内进行了研究，最大灵敏度为0.379％K ^-1。结果表明，Sr ₈ MgCe（PO ₄）₇：Tb ³⁺ 是一种用于固态照明和温度感应的有吸引力的颜色可调荧光粉。
