Abstract
An electroluminescent substance suitably comprising a conducting material such as a conducting oxide and at least one light-emitting dopant is disclosed. Preferred embodiments of the electroluminescent substance include rare earth dopants present within the conducting oxide such that the dopant materials generate light when electrically stimulated. Common dopant materials include erbium, ytterbium, praseodymium and other rare earth elements. The electroluminescent material is suitable for use, for example, in an electronic display or as a light source for many applications including Sagnac rotation sensors such as fiber optic gyroscopes.
