Abstract:

CdSe hexagonal nanoflakes have been synthesized via a reaction of CdCl2- oleylamine with Se-tri-n-octylphosphine at 300°C for 30min. The CdSe hexagonal nanoflakes with the typical side lengths of 9.5 to 12.3nm are single-crystalline wurtzite structure and are enclosed by {001} top and down surfaces. Size control of the CdSe nanoflakes from 3.3 to 18.6 nm is achieved by adjusting reaction temperature and time, and the size-dependent absorption and photoluminescence properties are observed. The formation of CdSe hexagonal nanoflakes results from the selective adsorption of oleylamine on the (001) prismatic facet. The as-obtained CdSe nanoflakes with exposed {001} facets show higher photocatalytic activity than CdSe commercial powders for degradation of malachite green. The present study motivates us to further explore new synthetic methods for the preparation of other II-VI semiconductor with a high percentage of reactive facets.
