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

Abstract

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 mm 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.
