We report a precise approach to take controlling of luminescence color in carbon nanoparticles (NPs) through charged-beam irradiation. The structural properties of the ion-beam irradiated CDs were investigated by ultraviolet-visible absorption spectra and Raman scattering experiments. From the conductive atomic force microscope experiments of the single unit of carbon NPs, the electrical properties of the pristine carbon NPs were transferred from highly conducting states to semiconducting or insulating states through the increasing of ion-beam energy and dosage. From the LCM PL images and spectra of the carbon NPs, we observed significant controlling of the LCM PL characteristicsin the high-energy ion-beam irradiated carbon NPs when increasing the ion-beam dosage. Based on these results, we found that the optical properties of carbon NPs had been successfully controlled by the ion-beam irradiating conditions. |
