Fabrication of semiconductor nanoparticles using electro spray deposition method

ZnS semiconductor nanoparticles were fabricated using electro spray process. We chose the electro spray deposition (ESD) method which is one of a particle preparation process from spray pyrolysis route. The ESD method, which produces nano-size droplets, combined with the evaporation of solvent of nano droplets can fabricate nanoparticle whose size are controlled to single nano order size and behave a quantum confinement effect. We successfully obtained 3.7 nm as the average size and 2.3 nm as the FWHM by precise controlled for the nozzle tip size and the applied voltage to 25 μm and 2.3 kV, respectively.
