Abstract: | Tungsten (W) photonic crystals are very attractive because of their potential applications in the conventional lighting field.
In this work we show that W nanostructures have dominative effects on optical properties of W inverse opal. The nanoparticle
structure of W phase can cause intensive optical absorption and breakdown of the photonic band gap; on the contrary, W inverse
opal made from bulk and compact W phase would have weak absorption and possess a good photonic band gap. The results will
throw a new light on the study and application of W photonic crystals and development of other photonic crystal and black-body
materials.
