Abstract
We report a low temperature fabrication and light-emitting characteristics of inorganic electroluminescent (EL) devices in which a CdSe/ZnS quantum dot (QD) layer was formed by a new ion beam deposition process. The deposition process was developed for fabrication of surfactant- and solvent-free QD structured films from colloidally dispersed QD solution. The electroluminescence spectra of the alternating field driven devices were found to be identical to the photoluminescence spectra of the source solution. The finding paves the way for the development of full color, transparent, flexible, and low-cost large area flat panel displays.Keywords
