  2. 16. Fabrication of inverse opal oxide structures for efficient light harvesting

    Author : Delphine Lebrun; Lars Österlund; Gunnar Niklasson; Vassilios Kapaklis; Herman Högström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; photonic; inverse opal; metal oxide; opal; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Abstract : Artificial opals are self-assembled face centered cubic (fcc) structures of  spherically shaped beads, which interesting applications as photonic band gap materials. Inverse opals are photonic crystals consisting of fcc paced voids of a low refractive index material imbedded in a high refractive index material. READ MORE
