In　this　paper,　Eu3+-activated　Sr2ZnGe2O7　(SZGO)　phosphors　were　prepared　by　a　traditional　solid-state　synthesis　method.　These　phosphors　exhibit　two　intense　emission　band　around　615　nm　(red)　and　704　nm　(deep　red)　under　excitation　at　394　nm.　The　dependences　of　the　emission　intensities　on　Eu3+　concentration　was　analyzed.　The　optimum　doping　concentration　of　Eu3+　for　the　phosphor　is　about　5　mol%.　Besides,　the　SZGO:　Eu3+　phosphor　shows　fluorescence　tunable　properties　between　615　nm　and　704　nm　as　the　concentration　of　Eu3+　increasing.　The　results　show　that　the　SZGO:　Eu3+　phosphor　may　be　applied　in　near　ultraviolet　pumped　plant　growth　LEDs.　©　2020
