Bio-Inspired Moth Eye Nanostructures (IMAGE) Optica Caption (a) This image shows the self-assembly of SiO2 nanoparticles on the top of high index light extraction layer Si3N4, which is deposited on Lu2SiO5:Ce thin film. (b) This is a scanning electron microscope image of the improved bio-inspired moth eye nanostructures with certain degree roughness on the sidewall, which shows interesting nano-on-nano features.
