Researches on tunable luminescence and temperature sensitivity of phosphors have become an increasingly popular trend. This paper reports a series of Ca₂YZr₂Al₃O₁₂ (CYZA):Bi³⁺, Sm³⁺ phosphors prepared by solid-state reaction. The phase purity, energy transfer, luminescent properties and temperature sensing performance of the phosphors have been carefully studied. CYZA:Bi³⁺, Sm³⁺ phosphors excited by ultraviolet light show tunable color emission, and the color shifts from dark blue to pink due to Bi³⁺→Sm³⁺ energy transfer. The related luminescent mechanism of phosphors is also explained. In addition, according to the different thermal sensitivity of Bi³⁺ and Sm³⁺, the temperature sensitivity of the phosphors is studied by fluorescence intensity ratio model. The maximum values of absolute sensitivity and relative sensitivity reach up to 0.099% K⁻¹ at 423 K and 0.356% K⁻¹ at 473 K, respectively. These findings indicate that CYZA:Bi³⁺, Sm³⁺ phosphors are potential candidates for tunable luminescence and temperature sensing.

对荧光粉的可调发光和温度敏感性的研究已成为日益流行的趋势。本文报道了一系列通过固相反应制备的Ca ₂ YZr ₂ Al ₃ O ₁₂ (CYZA):Bi ³⁺ , Sm ³⁺荧光粉。已经仔细研究了磷光体的相纯度、能量转移、发光特性和温度传感性能。CYZA:Bi ³⁺ , Sm ³⁺荧光粉在紫外光激发下显示出可调的颜色发射，并且由于Bi ³⁺ →Sm ³⁺颜色从深蓝色转变为粉红色能量转移。还解释了荧光粉的相关发光机理。此外，根据Bi ³⁺和Sm ³⁺的不同热敏性，利用荧光强度比模型研究了荧光粉的温度敏感性。绝对灵敏度和相对灵敏度的最大值分别在423 K和473 K时达到0.099% K ^-1和0.356% K ^-1。这些发现表明CYZA:Bi ³⁺、Sm ³⁺磷光体是可调发光和温度传感的潜在候选者。
