Abstract：

CaSnO3　doped　Eu3+　has　prepared　by　high-temperature　solid-state　reaction.　X-ray　diffraction,　scanning　electron　microscopy,　photo-luminescence　spectra　were　employed　to　characterize　its　property.　The　influence　of　concentration　of　Eu3+,　different　flux　and　charge　compensation　ions　on　the　luminescence　performance　were　studied.　The　excitation　and　emission　spectra　show　that　red　phosphor　CaSnO3:Eu3+　can　be　effectively　excited　by　near-ultraviolet　light　at　395nm　and　the　emitted　radiation　was　dominated　by　a　red　emission　peak　at　614nm　due　to　the　non-centrosymmetric　nature　of　the　Eu3+　site.　The　Commission　International　de　L＇Eclairage(CIE)　chromatic　coordinates　and　color　purity　were　calculated.　CaSnO3:Eu3+　phosphor　will　be　a　better　candidate　for　white　light　LED.
