Notes:
The synthesis of high-quality monodispersed nanocrystal is very important. Typicalsynthetic method is rapid nucleation by injection of an organometallic precursor into a solventmaintaining the reaction temperature. Since these methods are discontinuous processes, they are notefficient for large-scale production of monodisperse nanocrystals. In this study, continuousmicrochannel reaction technique is presented for synthesis of monodisperse lead selenidenanocrystals in a diphenyl ether as high-temperature organic media. The microchannel reactor wasused due to its possibility of continuous process and reproducibility of narrow size distribution innanocrystal synthesis. The synthesis was carried out in microchannel reactor (800 μm diameter) madefrom PTFE. Lead oleate and TOP-Se were used as organic precursor and diphenyl ether ashigh-temperature organic solvents. Lead selenide particles with a size of less than 10nm could becontinuously prepared by this method. The nanocrystals have been characterized by X-ray diffraction,TEM and optical absorption spectrometer
