Hybrid nanostructures are attractive for future use in a variety of optoelectronic devices. Self-assembled hybrid organic/quantum dots can couple quantum properties to semiconductor devices and modify their functionality. These devices are simple to fabricate and control, however they usually demonstrate low quantum efficiency. In this work we present experimental results of large extinction enhancement from a monolayer of colloidal quantum dots using a thin gold film evaporation forming random gold nano-particles that act as plasmonic antennas. The random structures guarantee no sensitivity to polarization changes. The fabrication process of the plasmonic gold nano particles is simple, cheap, and can be easily integrated with existing semiconductor devices. By matching the plasmonic resonance and the colloidal quantum dots bandgap we achieve up to 16% light extinction, which is 13 times fold enhancement, compared to the reference. These results may pave the way towards realizing more efficient and sensitive photon detectors.
