This　paper　reported　the　beta-Ga2O3　nanofibres　which　fabricated　by　electrospinning,　and　then　calcining　in　oxygen　at　750,　850,　950　and　1050　degrees　C.　The　structure　and　properties　of　beta-Ga2O3　nanofibers　have　been　studied　though　kinds　of　methods　such　as　XRD,　Photoluminescence　(PL)　spectrum,　Raman　spectrum,　Scanning　electron　microscope　(SEM)　and　FT-IR.　The　diameters　of　these　nanofibres　are　from　60　to　130nm　and　the　lengths　of　these　nanofibres　are　about　couple　millimetres.　The　spectrum　of　PL　which　excitation　at　365nm　gave　us　the　information　that　the　emission　peak　of　these　beta-Ga2O3　nanofibres　is　about　470nm,　it　may　be　coursed　by　the　various　defects　including　the　vacancies　of　gallium　and　oxygen　and　the　gallium-oxygen　vacancy　pairs　as　well,　and　observed　that　with　the　increasing　of　the　annealing　temperature,　the　emission　peaks　have　a　small　bule　swifting,　and　the　crystallinity　become　better　at　the　same　time.
