Electroluminescent devices
First Claim
1. An electroluminescent device comprising:
- a first charge carrier injecting layer for injecting positive charge carriers;
a second charge carrier injecting layer for injecting negative charge carriers; and
a light-emissive layer located between the charge carrier injecting layers and comprising;
a first component for accepting positive charge carriers from the first charge carrier injecting layer;
a second component for accepting negative charge carriers from the second charge carrier injecting layer; and
a third, organic light-emissive component for generating light as a result of combination of charge carriers from the first and second components;
the first, second and third components being combined into a single molecule; and
at least one of the first, second and third components forming a type II semiconductor interface with another of the first, second and third components.

Abstract
An electroluminescent device comprising: a first charge carrier injecting layer for injecting positive charge carriers; a second charge carrier injecting layer for injecting negative charge carriers; and a light-emissive layer located between the charge carrier injecting layers and comprising a mixture of: a first component for accepting positive charge carriers from the first charge carrier injecting layer; a second component for accepting negative charge carriers from the second charge carrier injecting layer; and a third, organic light-emissive component for generating light as a result of combination of charge carriers from the first and second components; at least one of the first, second and third components forming a type II semiconductor interface with another of the first, second and third components.
