Abstract

Ho/Yb-codoped Ba_0.77Ca_0.23TiO₃ ferroelectric ceramics were prepared by a solid-state reaction method. Under the excitation of 980 nm, all the samples exhibited strong green, red and near-infrared upconversion emissions. Upconversion emission intensities of the Ho/Yb-codoped Ba_0.77Ca_0.23TiO₃ ferroelectric ceramics can be enhanced with moderate Yb addition. Additionally, optical temperature sensing properties based on the upconversion emissions of the Ba_0.77Ca_0.23Ti_0.975Ho_0.005Yb_0.03O₃ ferroelectric ceramics were also investigated. The result demonstrated that the optical temperature sensor can be operated in the temperature range of 93-300 K with a maximum sensitivity of about 0.0053 K^-1 at 93 K. Compared with other rare-earth doped materials, it is much easier and cheaper to synthesize Ho/Yb-codoped Ba_0.77Ca_0.23TiO₃ ferroelectric ceramics.
