Complex　perovskite　PbTiO3-Bi(Me＇Me　＇＇)O-3　solid　solutions　represent　new　materials　systems　that　possess　a　higher　Curie　temperature　(T-C)　than　the　relaxor-PbTiO3　solid　solutions,　and　are　useful　for　potential　applications.　To　this　end,　novel　ferroelectric　single　crystals　of　the　(1-x)PbTiO3-xBi(Zn2/3Nb1/3)O-3　(PT-BZN)　solid　solution　were　successfully　grown　by　the　high-temperature　solution　growth　(HTSG)　method.　Powder　X-ray　diffraction　shows　that　the　symmetry　of　the　grown　crystals　is　tetragonal.　The　dielectric　permittivity　and　optical　domain　structures　were　characterized　by　dielectric　measurements　and　polarized　light　microscopy,　respectively,　as　a　function　of　temperature,　revealing　a　first-order　ferroelectric-paraelectric　phase　transition　at　a　T-C　of　436　+/-　2　degrees　C.　Based　on　the　T-C,　the　average　composition　of　the　crystal　platelet　was　estimated　to　be　0.58PT-0.42BZN.　Piezoresponse　force　microscopy　measurements　of　the　phase　and　amplitude　as　a　function　of　voltage　reveal　the　complex　polar　domain　structure　and　demonstrate　the　ferroelectric　switching　behaviour　of　these　materials.　These　results　suggest　that　the　PT-BZN　single　crystals　indeed　form　a　new　family　of　high　T-C　piezo-/ferroelectric　materials　which　are　potentially　useful　for　the　fabrication　of　electromechanical　transducers　for　high-temperature　applications.　(C)　2018　Elsevier　B.V.　All　rights　reserved.
