Abstract：

The　single　phase　full　color　phosphors　of　Dy3+-doped　Ca6Sr4(Si2O7)3Cl2　were　synthesized　by　a　solid-state　reaction　method.　The　as-synthesized　phosphors　were　characterized　by　X-ray　diffraction　and　photoluminescence　spectroscopy.　These　phosphors　can　be　efficiently　excited　in　a　near　ultraviolet　light　of　350　nm.　The　influences　of　sintering　temperature,　doping　content　and　charge　compensators　(Li+,　Na+　or　K+)　on　the　emission　intensity　were　investigated.　The　results　show　that　the　most　intensive　emission　intensity　of　the　Ca6Sr4(Si2O7)3Cl2:Dy3+　phosphor,　which　is　prepared　with　Na+　ions　at　the　sintering　temperature　of　950　℃　and　the　Dy3+doping　content　of　4.0　%　mole　fraction,　can　be　obtained.　It　is　indicated　that　Ca6Sr4(Si2O7)3Cl2:Dy3+　can　be　used　as　a　promising　luminescent　material　for　near　ultraviolet(NUV)-based　white-emitting　diodes.　©,　2015,　Chinese　Ceramic　Society.　All　right　reserved.
