Sol-derived BeO/air photonic structures

We present a sol-gel derived photonic structure of beryllium oxide. A new low temperature synthesis route has been developed to produce beryllium oxide from beryllium alkoxide. The beryllium alkoxide was prepared from beryllium metal, methyl mercury and butyl alcohol as starting materials. The samples have been mathematically modelled and their IR reflectance characteristics in the 2-18 μm wavelengths rang has been measured.
