Singlet Exciton Fraction in Electroluminescence from Conjugated Polymer
Abstract The efficiency of electrofluorescent polymer light-emitting diodes is determined by singlet exciton fraction (χS) formation and its value still remains controversial. In this work, χS in spiropolyfluorene (SPF) is determined by analyzing transient emission of phosphor-dopant probe. The χS i...
