Phase-controlled one-dimensional shape evolution of InSe nanocrystals

J Am Chem Soc. 2006 Nov 22;128(46):14780-1. doi: 10.1021/ja0660711.


Cubic-phase InSe nanowires were synthesized. Obtaining an appropriate high reaction temperature for formation of nanocrystals using poor solubility of Se powder in oleylamine induced the generation of unusual cubic phase of InSe to form nanowires. In comparison, hexagonal-phase nanoplates were formed by dissolving Se powder in oleylamine before increase of reaction temperature. The diameter of highly monodisperse wires was controlled by varying the amount of Se.
