Different　morphologies　of　nanostructured　bismuth　sulfide　(Bi2S3)　including　Bi2S3　nanoparticles,　nanorods　and　bundles　of　nanorods　have　been　prepared　successfully　by　an　ultrasonic-assisted　liquid　phase　method　and　hydrothermal,　surfactant-assisted　solvothermal　method,　respectively.　The　products　were　characterized　by　the　techniques　of　X-ray　diffraction　(XRD)　and　transmission　electron　microscopy　(TEM).　The　results　showed　that　reaction　time,　temperature　and　the　use　of　surfactant　would　affect　the　morphologies　of　resulting　products　remarkably.　The　mechanisms　that　form　these　different　morphologies　of　nanostructured　Bi2S3　were　also　discussed.　(C)　2003　Elsevier　Science　B.V.　All　rights　reserved.
