This paper reports our work in the application of localized surface plasmon (LSP) and non-radiative energy transfer (NRET) mechanisms in micro LEDs (μLEDs). μLEDs with the dimension of 40 μm × 60 μm and dry-etched nanoholes (NHs) in the mesas were fabricated. The metal nanoparticles (NPs) and color converting quantum dots (QDs) were filled into the NHs etched through the active region. Through the final optical measurements, the results are quite gratifying. This scheme is expected to promote the development of full-color displays in the future, achieving more efficient display technology based on μLEDs.
