The　lead-free　multifunctional　ceramics　Sm3+-doped　(Ba0.85Ca0.15)(Ti0.9Zr0.1)O(3　)were　synthesized　via　conventional　sintering.　The　influences　of　Sm3+　concentration　on　phase　structure,　grain　size,　Curie　temperature,　ferro-/piezoelectric　properties,　as　well　as　photoluminescence　(PL)　performances　of　the　ceramics　have　been　investigated.　The　results　show　that　with　the　Sm3+　concentration　of　0.4　mol%,　the　integrated　optoelectronic　performances　are　best.　In　order　to　further　study　the　relationship　between　ferroelectric　and　PL　features,　the　poling　effect　on　PL　intensities　of　the　ceramics　has　been　focused　on,　giving　the　highest　enhancement　factors　of　52.6%　induced　by　both　lattice　distortion　and　phase　transformation.　The　electric　poling　is　an　effective　route　to　enhance　the　PL　performance　of　luminescent　ferroelectrics.
