The photonic crystal slab shows an enhanced intensity of photoluminescence due to the nanohole pattern array producing Fabry-Perot like interference. A rough surface of nanoholes results in a broad spectrum with a small oscillation, and well-ordered multiple facets of nanoholes results in a relatively sharp spectrum with a large oscillation.
