Temperature sensing properties of dual-laser excited Y2O3:Yb3+/Er3+/Tm3+ fluorescent crystals
This paper synthesized Y2O3: Yb3+/Er3+/Tm3+ fluorescent crystals (YET) by annealing using the laser zone melting method. When the 365 nm(UV) and 980 nm(IR) lasers are excited together, the luminescence color of YET can be changed by adjusting the laser power. It can be adjusted between orange-red, yellow-green, and white. The temperature sensing characteristics based on the fluorescence intensity ratio (FIR) of non-thermally coupled levels (NTCL) and thermally coupled levels (TCL) of Tm3+ and Er3+ ions were studied. The derived maximum relative sensitivity (SR) reached the impressive value of 10.871 K-1 (303 K) and 0.511 %K−1 (563K), respectively. Moreover, as the temperature increases, the luminescence of the YET emission changes from white to blue. So, the luminescence emitted by YET can be adjusted between red, green, blue, and white. Therefore, using dual lasers to excite fluorescent materials can provide a suitable method for color-adjustable phosphor.
