Abstract	Rare-earth elements Dy$^{3+}$, Er$^{3+}$, Eu$^{3+}$ and Pr$^{3+}$-doped (K$_{0.5}$Na$_{0.5}$)NbO$_{3}$ ceramics were prepared by traditional solid-state sintering method. The structure, piezoelectric, ferroelectric and photoluminescence properties of the samples were investigated. All ceramics possessed orthorhombic perovsktie structures at room temperature without impurity phases. The ceramics were well sintered and displayed considerably dense microstructure and inhomogeneous grain size distributions. Good ferroelectricity could be realized in the proposed compositions. All KNN-RE ceramics exhibited photoluminescence effects. The KNN-Pr sample showed little degradation in both switchable polarization and the converse piezoelectric coefficients d $_{33}$* after 10$^{5}$ switching cycles, meanwhile, it had the highest photoluminescence intensity. The work provides an alternative routine to develop new multifunctional materials.
