A　series　of　emission-tunable　Ca3SiO4Cl2:Bi3+,　Li+,　Eun+(n　=2,　3)　(CSC:Bi3+,　Li+,　Eun+)　phosphors　have　been　synthesized　via　sol-gel　method.　The　X-ray　diffraction　results　indicate　that　the　as-synthesized　phosphors　crystallize　in　a　low　temperature　phase　with　the　space　group　of　P21/c.　Energy　transfer　from　Bi3+　to　Eu3+/Eu2+　exists　in　CSC:Bi3+,　Li+,　Eun+　phosphors.　Under　the　excitation　of　327　or　365 nm,　the　Ca2.98−ySiO4Cl2:0.01Bi3+,　0.01Li+,　yEun+(y=0.0001–0.002)　phosphors　show　an　intense　green　emission　band　around　505 nm,　while　under　the　excitation　of　264 nm,　three　emission　bands　centered　around　396 nm　(Bi3+),　505 nm　(Eu2+)　and　614 nm　(Eu3+)　are　observed　and　tunable　colors　from　blue-violet　to　green　or　white　are　achieved　in　these　phosphors　by　varying　the　content　of　Eu.　White-light　emission　with　the　color　coordinate　(0.312,　0.328)　is　obtained　in　Ca2.978SiO4Cl2:0.01Bi3+,　0.01Li+,　0.002Eun+(n　=2,　3).　Based　on　these　results,　the　as-prepared　CSC:Bi3+,　Li+,　Eu2+,　Eu3+　phosphors　can　act　as　color-tunable　and　single-phase　white　emission　phosphors　for　potential　applications　in　UV-excited　white　LEDs.　©　2016　Elsevier　Ltd　and　Techna　Group　S.r.l.
