Scope

This document describes the testing methods for the optical properties of organic light-emitting materials. The fluorescence spectrum, phosphorescence spectrum, and UV-visible absorption spectrum are tested using solutions or thin films; the refractive index and extinction coefficient of the materials are tested using thin film samples; and the electroluminescence characteristics of organic light-emitting diode displays are tested, including color coordinates, brightness, luminous efficiency, and brightness aging performance.
This document is applicable to the research and development, application verification, and inspection and testing of various types of organic light-emitting materials.
