Abstract
We fabricated an InGaN based nanorod LED structure with colloidal quantum-dot (QD) phosphors deposited in between the nanorods, creating side-wall coupling between QD phosphors and InGaN multiple-quantum-well (MQW) emitters. Time-resolved photoluminescence measurements for nanorod structures with and without colloidal QD coating were performed to study the direct MQW-to-QD non-radiative energy transfer.
