At present, due to the advantages of non-contact, fast response, high precision, etc., the realization of temperature sensing technology based on the fluorescence intensity ratio has become the focus of the research field of temperature measurement. Here, we successfully prepared Bi³⁺ and Eu³⁺co-doped luminescence material and studied its temperature sensing performance. The absolute sensitivity and relative sensitivity of the LaB₃O₆: Bi³⁺, Eu³⁺ sample reached 0.008 K⁻¹ and 0.579% K⁻¹ at 423 K, respectively. This work adds new candidate to the family of Bi³⁺ and Eu³⁺ co-doped temperature sensing materials.
