Angular Dependence of the Emission from a Conjugated Polymer Light‐Emitting Diode: Implications for efficiency calculations
Abstract
The ability to compare electroluminescence efficiencies is important now that light‐emitting diodes (LEDs) have been constructed using many different polymers and different device structures. Various ways of defining and measuring the efficiency of polymer LEDs are discussed, revealing the need to understand the nature and orgin of the angular dependence of the emission. A model for the angular distribution of the emitted light is proposed and measurements of the ligh output of a polymer LED described whose results are consitent with the model.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
