Abstract
A simple method of measuring the external quantum efficiency of organic electroluminescent (EL) devices has been investigated. Assuming a perfectly diffusive EL emission surface, this method enables the external quantum efficiency to be calculated from the conventionally measured parameters: luminance, EL spectrum, and current. Its use is limited to EL emission in the visible wavelength range.Keywords
