摘要：
To investigate the effect of Er3+ doping on the luminescence behavior of perovskite structure ceramics, the Er2O3 doped KNbO3 smart ferroelectric ceramics have been synthesized by the conventional solid-state reaction. The results of luminescence property demonstrated that the green and red up-conversion emission intensities of these ceramics excited under 980 nm increased with the content of Er2O3 and achieved the maximum value with Er2O3 of 0.75 mol%. The ratio of green and red emission intensity could also be adjusted by changing the content of Er2O3, and the mechanism of up-conversion processes involved a two-photon absorption. In addition to the admirable intrinsic piezoelectric properties of KNbO3, this kind of material may render potential application as a multifunctional device by integrating its up-conversion and piezoelectric property.
