Abstract

Er3+-doped Ba0.5Sr0.5TiO3 (BST) powders were prepared by using barium nitrate, strontium nitrate, tetrabutyl titanate, and ammonia via citrate-nitrate combustion process, along with the XRD, DSC/TGA, and SEM analytic reports. The Er3+ luminescence intensity reached a maximum value in the sample with 3mol% Er3+ ions concentration sintered at temperature 1300°C. We also showed that 1mol% Er dopant improved the dielectric property of BST and the BST:Er materials may have potential use for electroluminescence devices.
