Application Of Porous Gan For Microled

We report loading quantum dots (QDs) inside nanoporous (NP) GaN and using NP-GaN as a color converter to fabricate micro-LEDs. A strong light scattering can be induced by NP-GaN and blue pumping light can be significantly absorbed by red and green QDs. More than 90% of light conversion efficiency has been achieved for both red and green QDs inside NP-GaN. Monolithic red, green, and blue color micro-LEDs have been achieved with loading red and green QDs into NP-GaN.
