description: The purpose of this work is to find and study new light-emitting nanocomposites of perovskite quantum dots (PQDs) embedded within a polyfluorene matrix. As part of this work, samples of light-emitting electrochemical cells with variations in the emission layer composition were produced and characterized. Cesium lead-halide PQDs are a promising light-emitting material due to their high quantum yield, narrow, intense, and tunable luminescence peak. The main problem is the ionic nature of these compounds, which causes the segregation effect intensified by agglomeration, to which PQDs in a solution are prone. In order to curb the segregation effect, PQDs are being embedded within a polyfluorene matrix that chemically and/or physically prevents their migration and agglomeration. We investigated three new polyfluorenes named B26, Bx4, and Bx5. Wolfram Mathematica and Origin Pro application software tools were used. Samples were constructed based on the PQDs/polyfluoren nanocomposites. The results of sample characterization revealed the most successful structure of the light-emitting electrochemical cell. It turned out to be the structure with the emission layer based on Bx5. The maximum electroluminescence intensity was 1370 /2, current efficiency was 25.2 /, power efficiency was 41.8 /. The position of the electroluminescence peak was found to be independent of either the applied voltage or the type of polyfluorene (position on the CIE 1931 colour space located at x=0.11, y=0.74).
