 This paper examined the properties of zinc oxide nanorots and their potential use in white light emitting diodes. It found that the presence of deep level centers in the nanorots caused them to emit visible light when connected to a p-type material such as silicon carbide or gallium nitride. The authors concluded that this combination could be used to create efficient white light emitting diodes for large area applications.
