Photoelectrical properties and surface examination of luminescent copolymer compounds

This work aimed to use copolymers in the production of organic light-emitting diodes, as well as to examine copolymers properties. Experimental optical absorption and fluorescence were determined, along with HOMO (the highest occupied molecular orbital) LUMO (the lowest unoccupied molecular orbital) levels. Refractive indexes and extinction coefficients were obtained using the ellipsometric spectroscopy method. Surface tests were performed using the atomic force microscope technique. The results of the molecular dynamics simulations are also presented. Light-emitting diodes were also produced, and their current-voltage and lighting-voltage characteristics were established.
