摘　　要：Te single-crystal nanotubes were synthesized using Na2TeO3 and (NH2)2CS as starting materials and pol-yacrymide (PAM) as morphology-director under hydrothermal conditions. The obtained products were characteri-zed by XRD, FESEM, SEM and TEM techniques. The results show that Te nanotubes grow along c axial with the inner diameters of 100~500 nm, wall thickness of 80~160 nm and lengths of 5~10 μm. A possible mechanism for the growth of Te nanotubes was discussed.Te single-crystal nanotubes were synthesized using Na2TeO3 and （NH2）2CS as starting materials and polyacrymide （PAM） as morphology-director under hydrothermal conditions.
