Fine control of the photoluminescence properties of CdSe nanoparticles (NPs) dispersed in CHCl3 is achieved by simple adjustment of the NPs concentration, and the wavelength of photoluminescence emission of CdSe NPs can be tuned within the nanometer accuracy. The mechanism of the process is proposed to be relevant to the modulation of the surface states of NPs by the concentration. This solution-based approach offers an attractive and complementary process to the conventional band gap engineering of semiconductor NPs with fine tunable optical properties.
Graphical abstractThe process of HDA adsorbed on and desorbed from CdSe nanoparticles (NPs) in CHCl3 can modulate the amount of the surface states of NPs by the concentration, which can be used to fine tune the photoluminescence of CdSe NPs.Figure optionsDownload full-size imageDownload as PowerPoint slide
