Abstract

High density nanoporous patterns were imprinted on bulk ZnO single-crystal substrates. The nanostemps were prepared via replication from nanoporous anodized alumina. Using the nanoimprinting technique, nanopatterns were successfully transferred onto the ZnO surface. Here we demonstrate that the light emitting efficiency of ZnO is highly enhanced through the simple nano-texturing. This simple method is applicable to any other light emitting diodes where the antireflective surface coating is desirable.
