It was established that the synthesized HPs are characterized by exciton photoluminescence, whose intensity increases at the replacement of iodine atoms with bromine and chlorine. It has been shown that the dispersing of the solid MAPbBr3 in the presence of the microquantity of organic amines (hexyl- or oleylamine) and oleic acid in toluene leads to the stable colloidal solutions formation with a quantum yield of photoluminescence ~ 57%. By dispersing MAPbBr3 in a polystyrene solution (PS) in toluene the stable colloidal solutions of the MAPbBr3/PS composite were obtained, from which it is possible to obtain MAPbBr3/PS films that are resistant to environmental factors and characterized by an exciton green luminescence with a quantum yield of ~ 46%, and its the value does not decrease with the increase in the concentration of polystyrene in the film.5481 Product Description popup.authors Конощук Наталія Володимирівна Посудієвський Олег Юлійович popup.nrat_date 2020-04-02 Close
