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 tempera- ture. 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 indi- cates that these nanocrystals were crystallized in the cubic structure with lattice a = 5.818 ?. The optical properties of the products are illustrated, and their possible forming mechanism is explored.
