摘要：

The synthesis and novel fabrication of quantum dot layers has been performed by using electrohydrodynamics atomization technique. The surface, optical and electrical properties of the fabricated films have been characterized by FE-SEM, TEM, spectroscopes and semiconductor device analyzer. The CdSe/ZnS core/shell quantum dots have been synthesized and dispersed in toluene and DMSO as cosolvents. The sprayed CdSegnS quantum dots have been employed as emissive layer. The conjugate polymers of PEDOT:PSS and MEH-PPV are used as the hole and electron transport layers. The thickness of emissive layer for hybrid device has been optimized by changing the standoff distance of electrohydrodynamics atomization system. The flexible hybrid device with optimized thickness of quantum dots showed red light at 634 nm wavelength in visible range with 165 mA/cm(2) current density and 2.2 lux of luminance at 15 V.
