Noncontact fluorescence temperature detection systems have become a significant research focus. In this study, a new Ba3Y(BO3)3 phosphor co-doped with Er3+/Yb3+ was successfully synthesized using a high-temperature solid phase method. The introduction of Yb3+ as a sensitizer enhanced the luminescence properties of the Ba3Y(BO3)3 phosphor. The occupation of Er3+ and Yb3+ ions in the crystal lattice was analyzed in detail. The up-conversion luminescence and underlying mechanisms were explained by the double logarithmic relationship between the luminescence intensity and pump power. The temperature sensitivity of the phosphors was explored in the range of 333-513 K using fluorescence intensity ratio technology based on the two green peaks (thermal coupling level Er3+). The temperature sensing S r reached 1.44 × 10-4 K-1 at 333 K, indicating that Ba3Y(BO3)3:Er3+,Yb3+ phosphors have potential applications as temperature sensors.
