Nanoimprinted photonic crystal using quantum dot embedded resin

Nanoimprinting can fabricate nanostructures with low manufacturing costs and high throughput, overcoming the limit of conventional fabrication. In this research, we fabricate a photonic crystal resonator composed of QDs and TiO2 nanoparticles using the nanoimprinting technique. The PL of the QDs is enhanced by coupling to high quality factor optical mode, which is supported by the photonic crystal consisting of no loss dielectric composite. We demonstrate the imprinted nanophotonic device can operate as an optical resonator to enhance the light-matter interaction. Additionally, this research can give a promising way for high-resolution QLEDs with luminescence enhancement.
