摘要：

Telluride　nanoparticles　were　prepared　by　inert-gas　condensation.　The　crystal　structure,　morphologies　and　particle　size　distribution　of　the　sample　were　characterized　by　X-ray　diffraction　(XRD),　transmission　electron　microscopy　(TEM),　and　laser　particle　analyzer.　The　results　indicate　that　the　prepared　nanoparticles　of　four　kinds　have　uniform　size,　high　purity,　narrow　size　distribution　and　spherical　shape.　As　the　working　pressure　is　from　30　to　5　kPa　at　constant　electric　current　of　50　A,　the　average　diameters　of　the　nanoparticles　of　Te　and　Bi　decrease　from　200　nm　to　20-80　nm.
