The dipole orientation in a light-emitting film can be extracted by the analysis of angular-dependent photoluminescence (PL). Setfos can analyze angular-dependent PL data collected by the gonio-spectrometer Phelos to get information about the properties of an organic emitter, such as the orientation of the dipoles and the width of the emission zone. With this analysis, we are able to optimize the characteristics of OLEDs and QDLEDS to obtain higher EQEs.
