One-step fabrication of Cd(OH)(2) nanorings via a solution phase synthesis

Cd(OH)(2) nanorings were synthesized in high yield via a one-step solution phase synthesis process at room temperature, in which the co-existence of ethanol and ammonia is the key factor for the formation of such a ring structure. Further calcination of the Cd(OH)(2) nanorings results in the formation of CdO nanorings.
