Abstract

The optical properties of core-shell quantum dots (QDs) are important for optoelectronic devices and biological applications. In this study, we investigate the optical properties of core-shell CdSe/ZnS QDs embedded in PMMA polymer thin films. The luminescence from QD emission would be more applicable if the spatial distribution of the emission was controllable. We propose a method to control the emission distribution by modifying the nanostructure. A bi-periodic nanostructure was fabricated and characterized in hybrid QD thin films by a nano-imprint technique. The finite difference time domain method was used to simulate the electric field distribution in the measured structure. It is shown that the far-field distribution of the QD emission is controllable by manipulating the nanostructure of the hybrid QD thin films.
