Abstract
Semiconductor CdS nanotubes with a small ratio of length to diameter and nanospheres were simultaneously synthesized in the light of bio- mineralization process through living bio-membrane bi-template of mungbean sprouts at room temperature. The outside diameter of the nanotube is 220－ 240 nm and the inner diameter is 200－220 nm, the length is up to 600－700 nm and the ratio of length to diameter is 2:1. The nanoshpheres are 25 nm in diameter and well distributed. The XRD pattern indicates that these nanocrystals were crystallized in the cubic structure with lattice a = 5.818 Å. The optical properties of the products are illustrated, and their possible forming mechanism is explored.
