| Abstract: | Monodisperse surfactant-capped CdSe nanocrystals were prepared by th e pyrolysis of ligands of Se and Cd in a hot coordinating solvent.The CdSe nanoc rystals synthesized at different reaction times have been characterized by UV-V is and fluorescence (FL) spectra.Results of UV-Vis and FL spectra showed that t he CdSe nanocrystals prepared at the reaction time of 15 min exhibited the large st fluorescence intensity. |
