| Abstract: | Up-conversion phosphor is a potential candidate as non-contact temperature sensor because of its unjammable and unique detection abilities. In this work, we investigate the influence of Yb3+ concentration on the emission color, thermal sensing and optical heater behavior of Er3+ doped Y6O5F8 phosphor. Our results show that the emission color of Er3+ and Yb3+ co-doped Y6O5F8 powder changes from green to yellow with the Yb3+ concentration increasing. Importantly, the temperature sensing sensitivities of Er3+ and Yb3+ co-doped Y6O5F8 powder reach 0.008, 0.009, 0.010 and 0.011 K−1 as the sample doped with 2%, 5%, 8% and 11% Yb3+ at 476 K, respectively. Moreover, the temperature of high Yb3+ concentration sample shows preferable optical heating behavior, whose temperature is ascended by a large value of 94 K when the excitation pump power density changes from 1.0 to 13.1 W cm−2. These results suggest Er3+ and Yb3+ co-doped Y6O5F8 powder has great potential in colorful display, temperature sensing and optical heating. |
