METHOD OF PRODUCING PHOTONIC-CRYSTAL STRUCTURES BASED ON METAL OXIDE MATERIALS Russian patent published in 2013 - IPC C01G9/02 C01G19/02 B82B3/00 B82Y20/00 C30B29/16 G02B1/02

Abstract RU 2482063 C2

FIELD: chemistry.

SUBSTANCE: invention relates to opto- and microelectronics and can be used to make opal-like structures. The method of producing photonic-crystal structures based on metal oxide materials involves filling a template consisting of monodispersed micropheres of polystyrene, solutions of metal-containing precursors, followed by annealing the structure on air at temperature of 450-550°C for 8-10 hours. The precursors from which the structure is formed are saturated alcohol solutions of tin dichloride SnCl₂·2H₂O or zinc nitrate Zn(NO₃)₂·2H₂O.

EFFECT: invention enables to obtain photonic-crystal structures based on SnO₂ and ZnO with a photonic stop band in the visible or near infrared spectral range and porosity of not less than 85%.
