| titleOfInvention | METHOD OF MAKING INORGANIC PEROVSKITE NANOWHISKERS OF CsPbBr3 TYPE |
| abstract | FIELD: nanotechnologies.SUBSTANCE: invention relates to synthesis of nanostructures based on perovskites, which can be used as materials for nanophotonics to create Fabry-Perot nanosensors and photonic integrated circuits. Method for making insulated perovskite nanowhiskers CsPbBrincludes treatment of a glass substrate by polishing its surface with a mixture of chromium oxide CrOparticles with diameter less than 100 nm, glyceryl tristearate and oleic acid to create hydrophobic layer, followed by applying a solution of precursors of perovskite CsBr and PbBrto the substrate by spraying or spin-coating with formation of solution droplets, then substrate with said application is placed on bottom of vessel, placed in another vessel of larger size, which contains azeotrope: isopropyl alcohol-water (IPA⋅HO) and is at constant temperature of 50 °C, closing it with a cover and for final formation of nanowhiskers drying is carried out for 5–7 minutes until complete drying of solution drops.EFFECT: faster operation (production time reduced to 5–7 minutes), simplification and cheapening of manufacturing technology of high-quality inorganic perovskite nanowhiskers of CsPbBrtype with a longitudinal dimension of 2–50 mcm and a cross section of less than 1 mcm, characterized by low concentration of defect conditions, improved reflectivity of side surfaces and improved optical properties: high Q-factor Q=1,017–6,166 and low generation threshold P=13 nJ/cm.1 cl, 6 dwg, 1 ex |
