Abstract：Er3+ doped BaTiO3 powders co-doped with inequivalent ions at different sites were fabricated by solid-state reaction method. The upconversion luminescence properties were improved by using two methods based on charge compensation mechanism,including Er3 +/Li + co-doping at A-site and Er3 +/Nb5 + co-doping at B-site. The correlation between crystal structure and luminescence property reveals that there exist different luminescence mechanisms contributing to such enhancement. Compared to the Er3 +/Nb5 + doped sample,a more distinct enhancement in photoluminescence intensity was detected for Er3 +/Li + co-doped sample,which was mainly ascribed to the charge balance and the decrease of structure symmetry.
