Simultaneously inducing synthesis of semiconductor selenium multi-armed nanorods and nanobars through bio-membrane bi-templates

Multi-armed nanorods and nanobars of semiconductor selenium were simultaneously synthesized in the light of biomineralization process through bio-membrane bi-templates of rush at room temperature. The multi-armed nanorods are 60 nm in diameter and 1.5 mum in length; the nanobars are 150 nm in diameter and 1000-1100 nm in length. The XRD pattern indicates that these nanocrystals were crystallized in the hexagonal structure with lattice constants a 0.437 nm, c = 0.495 nm. The possible formation mechanism was investigated.
