Abstract

A study was conducted to demonstrated high quality three-dimensional (3D) metallic photonic-crystal structures can be made through a combination of colloidal-crystal templated electro-deposition and electroolishing. The structural openness (metal filling fraction (FF). Optical measurements demonstrated that metal inverse opals modulate the absorption and thermal emission of the metal and that these effects become 3D in nature at high degrees of structural openness. Nickel was selected for the process due to its high reflectivity in the infrared (IR), temperature stability, and better electrochemical processing. Nickel inverse opals were fabricated by uising electrodeposition through a polyestyrene (PS) opal template that was first deposited on a surface-treated gold (Au) film evaporated on a silicon wafer. The final thickness was occured over the sample surface.
