Synthesis of shape-controlled beta-In2S3 nanotubes through oriented attachment of nanoparticles

Beta-In(2)S(3) nanotubes were synthesized using an organic solution pyrolysis route. The shape of the beta-In(2)S(3) nanotubes was controlled from hexagonal nanoplates to nanotubes simply by changing the reaction time. The growth mechanism of the nanotubes was explained by oriented attachment. The beta-In(2)S(3) nanotubes had a diameter, wall thickness and length of 5.0 nm, 0.79 nm and >10 microm, respectively. The diameter of the beta-In(2)S(3) nanotubes was found to be dependent on the sulfur concentration.
