3D periodic microstructures of high-refractive index materials (see Figure)
, in particular the II-VI semiconductors CdS and CdSe, have been synthesize
d by electrodeposition through silica- or polystyrene-based colloidal assem
blies. The highest refractive index contrast is achieved after removal of t
he silica or polystyrene templates with HF or toluene, respectively.
