This work is focused on optical investigations of Sb–S–I glass photonic crystals based on three-dimensional opal template with a closed-packed face centered cubic (fcc) lattice prepared from monodisperse silicon (SiO2) spheres by gravity sedimentation. Three types of photonic structures have been examined: SiO2-opals, opals filled with Sb–S–I glass (direct opals) and Sb–S–I inverted opals obtained...
In this work we present three-dimensional photonic crystals of air spheres in antimony sulfoiodide (SbSI). The initial opal matrices with a face centered cubic (fcc) lattice, were prepared from monosized silicon spheres by gravity sedimentation. Composite opal-SbSI structures were obtained by infiltration of the voids in opals with melted SbSI. Two different cooling methods in processes of infiltration...
