Colloidal Nanocrystals Fluoresced by Surface Coordination Complexes
Colloidal Nanocrystals (NCs) with fluorescence originating from surface complexes are successfully prepared. The components of these NCs range from insulator, semiconductor to metal, with either pure phase, doped or core/shell structures. The photoluminescence of these NCs can be reversibly tuned across the visible to infrared spectrum, and even allow multi-color emission. A light emitting devi...

متن کاملTuning the Localized Surface Plasmon Resonance in Cu2–xSe Nanocrystals by Postsynthetic Ligand Exchange
Nanoparticles exhibiting localized surface plasmon resonances (LSPR) are valuable tools traditionally used in a wide field of applications including sensing, imaging, biodiagnostics and medical therapy. Plasmonics in semiconductor nanocrystals is of special interest because of the tunability of the carrier densities in semiconductors, and the possibility to couple the plasmonic resonances to qu...
متن کاملColloidal synthesis of germanium nanocrystals
In this study, colloidal germanium nanocrystals were synthesized by a simple and novel method, and their optical properties were also studied. Polyvinyl alcohol (PVA) as a surface modifier was used to control the optical properties of colloidal Ge nanocrystals. Fourier transform infrared spectroscopy (FTIR) analysis was performed to identify the various functional groups present in the sample. ...
متن کاملUltrafast Charge Dynamics in Trap‐Free and Surface‐Trapping Colloidal Quantum Dots
Ultrafast transient absorption spectroscopy is used to study subnanosecond charge dynamics in CdTe colloidal quantum dots. After treatment with chloride ions, these can become free of surface traps that produce nonradiative recombination. A comparison between these dots and the same dots before treatment enables new insights into the effect of surface trapping on ultrafast charge dynamics. The ...
