摘要

Color-conversion efficiency enhancement of hybrid light-emitting diodes (LEDs) by cadmium-free colloidal quantum dots (QDs) and a novel selective area nanocavities structure has been demonstrated. Combining nanoimprinting and photolithography techniques, nanocavities array can be fabricated at designated locations on the LEDs. The color-conversion efficiency of selective area nanocavities LED can ...
