Abstract
An organic light emitting device (OLED) comprises an anode; a cathode; and a light emitting layer, disposed between the anode and the cathode; wherein the light emitting layer comprises at least one luminescent compound; and wherein the transition dipole moment of the at least one luminescent compound is oriented parallel to the surface of the light emitting layer. A method of fabricating a light emitting layer, comprises the steps of providing a substrate; depositing less than 2 nm of a template material on the substrate; and depositing a composition comprising at least one light emitting compound on the template material.
