description: The work is devoted to the study of luminescent properties of low-dimensional crystals of CsPbBr3 phase obtained in polymeric matrix based on polyurethane. Photoluminescence spectra of the non-polymerized polyurethane solution, the obtained film and the dissolved film were obtained by excitation with an ultraviolet lamp and a semiconductor laser with a wavelength of 405 nm. A process was performed to optimize the synthesis of solutions with luminescent particles by selecting the most suitable polar solvent. The experimental results of the work were the time dependences of the luminescence spectra for each of the obtained objects. It was found that toluene should be used as a co-solvent for nucleation of the bromide perovskite crystal phase in a solution of polyurethane and dimethylformamide, with the position of the luminescence band maximum shifted from 515 to 521 nm over 30 days of observation; polyurethane film with CsPbBr3 particles has two bands of luminescence around 463 and 521 nm, and the spectra themselves by the relative intensity of the bands are close to those of standard white LEDs based on aluminum- yttrium garnet (Ce YAG). The work was carried out at the Department of Applied Chemistry, The Institute of Metallurgy, Mechanical Engineering and Transport, Peter the Great St. Petersburg Polytechnic University.
