Abstract

The color-tunable upconversion (UC) emission and optical temperature sensing behaviour was observed from the Er-Yb-Mo codoped Bi7Ti4NbO21 (BTN) ferroelectric oxide. By control of the Mo concentration, the ceramics are capable of generating color tunability from green to yellow, then to red. The optical temperature sensing behaviour of green and red UC emission was studied using the temperature fluorescence intensity ratio (FIR) technique at temperature region from 133 to 450K, showing a relatively high sensitivity. The experimental data fitted a linear function very well, which suggests that the oxides could be used for optical temperature sensing applications. The polarization-electric field (P-E) hysteresis loops have been investigated, indicating it maintained ferroelectric properties with doping. Based on the profiles of XRD, Rietveld refinement and the XPS analysis, the structure variety by Er-Yb-Mo codoping and mechanism responsible in color-tunable UC emission were discussed in detail.
