摘要：
In this paper, SrMoO4: Er3+ phosphor excited by 976 nm diode laser shows remarkably intense green and relatively weak red upconversion emissions. Subsequently, within the temperature range from 310.8 K to 629.4 K, we tested a temperature-dependent fluorescence intensity ratio originating from the thermally coupled H-2(11/2) and S-4(3/2) states. It is revealed that SrMoO4: Er3+ phosphor exhibits a high sensitivity of 0.0326 K-1 at 554.0 K, indicating that the phosphor can be regarded as a promising building block for optical temperature sensor.
