Abstract

Er3+/Yb3+-doped NaGdF4 crystal-implanted fiber (CIF) is synthesized by the electrospinning technique, which possesses excellent crystal dispersibility, glorious flexibility, and high crystal utilization, realizing temperature sensing in complex and harsh environments. The combination of main and auxiliary sensing endows CIF with self-calibration functionality to realize accurate temperature measurement. Serving as the main thermal response signal for a noninvasive nanothermometer, the absolute and relative sensitivities for effective green emissions are up to 0.446% K-1 at 423 K and 1.018% K-1 at 303 K, respectively. Further, the introduction of a blue emission peak is to participate in the thermal response as an auxiliary indicator to inspect the accuracy of the main thermal sensing data where the absolute and relative sensitivities reach 28.473 and 1.522% K-1 at 313 and 303 K, respectively. The flexible CIF with cooperative response thermometry possesses a broad prospect in nanodomain optical thermometers, which present extraordinary potential in nondestructive temperature monitoring and flexible temperature sensing elements.
