Abstract	Herein, a new up-conversion temperature sensor of LiCaLa(W0.1Mo0.9O4)(3):0.04 Er3+/0.1Yb(3+) phosphors that exhibit strong luminescence intensity, improved and good repeatable temperature sensing performance and stability, was reported for the first time. All samples show typical tetragonal scheelite structures and exhibit typical up-conversion luminescence. Three distinct emission bands correspond to two strong green (H-2(11/2)/S-4(3/2) -> I-4(15/2)) and a weak red (F-4(9/2) -> I-4(15/2)) bands, respectively. WO42- and MoO42- with similar properties can be replaced with each other to improve the crystal field and ultimately improve the luminescence efficiency. Interestingly, the fluorescence intensity ratios of the two sublevels (S-4(3/2(1)) and S-4(3/2(2))) and H-2(11/2) increase with the increase of temperature, indicating the improvement of temperature sensing performance. The S-A-(ma)x are 0.0134 K-1 and 0.0104 K-1, and S-R(-)ma(x) are 0.0434 K-1 and 0.0548 K-1 for H-2(11/2)/S-4(3/2(1)) and H-2(11/2)/S-4(3/2(2)), respectively. Therefore, the tungstate-molybdate up-conversion luminescence materials has a potential application prospect of optical temperature sensor.
