Abstract
Organic white-light-emitting blend materials were prepared by light-doping method and electroluminescent devices fabricated using the same, including a transparent substance, translucent electrode, white-light-emitting layer and metal electrode in order, can efficiently control Förster energy transfer in organic light-emitting materials by performing light doping, thus to fabricate a white electroluminescent device using the blend materials which can emit white-light with high efficiency. The white-light-emitting blend materials can be obtained by the light-doping method, in which the energy transfer occurs only between a host which is a donor and each dopant which is an acceptor, while the energy transfers between dopants are efficiently blocked.
