采用高温固相法合成了ALn(MoO4)2∶3%Er3+(A=Na,K; Ln=La,Y)荧光粉，采用XRD对荧光粉的晶体结构进行了表征。荧光光谱分析表明荧光粉可被380 nm可见光及274 nm近紫外光有效激发而产生下转换发射。在380 nm激发下，Er3+离子4S3/2和2H11/2能级发射存在温度猝灭现象。探讨了基质成分对荧光温度猝灭特征温度T0的影响，发现基质成分对特征温度有较大影响，KLa(MoO4)2∶3%Er3+的温度稳定性最好。利用荧光强度比（FIR）方法研究了Er3+离子的温度传感特性，研究了基质成分对温度传感的绝对灵敏度的影响，发现NaY(MoO4)2∶3%Er3+的温度传感绝对灵敏度最高。

ALn(MoO4)2∶3%Er3+ (A=Na, K; Ln=La, Y) phosphors were prepared via a high temperature solid state reaction, the crystal structure of the obtained phosphors was characterized by XRD technique. The results of photoluminescence spectra indicated that the phosphors could be effectively excited by 380 and 274 nm and evoked downconverion emissions. Temperature quenching behavior was observed in the phosphors under 380 nm excitation. The influence of host on the characteristic temperature of fluorescence emission was studied, and it was found that the host greatly affected the characteristic temperature and that KLa(MoO4)2∶3%Er3+ phosphor presented a good luminescence temperature stability. The fluorescence intensity ratio (FIR) was applied to study the temperature sensing property. The host dependence of absolute sensitivity of temperature sensing was investigated and NaY(MoO4)2∶3%Er3+ phosphor was confirmed to have higher absolute sensitivity than the others.
