Photochemical size reduction of CdSe and CdSe/ZnS semiconductor nanoparticles assisted by n pi* aromatic ketones.
A novel effect of n pi* aromatic ketones on the quantum dots optical properties is reported. By controlling experimental conditions such as time of irradiation, presence of air in the media, hydrogen donor capacity of the solvent, and irradiation wavelength, core and core-shell CdSe QDs can be resized as convenient.
