Method for selecting combination of host material and light-emitting material, and organic light-emitting device using combination selected thereby

摘要

A method for selecting a combination of a host material and a light-emitting material to be used for a light-emitting layer of an organic light-emitting device, comprising the steps of: (a) disposing a mixture film containing a host material and a light-emitting material on a substrate; and (b) evaluating the mixture film with respect to light-emitting properties while irradiating a light that is absorbed by the host material to the mixture film. An organic light-emitting device comprising a light-emitting layer containing the combination of the host material and the light-emitting material selected by the method is also provided.
