- Abstract
A model is proposed for a new type of optoelectronic device that utilizes the luminescence of a film of ta-C:H in the plane of a fused quartz substrate. It is observed that the luminescence radiation propagating in the interior of the substrate becomes highly monochromatized. However, along the normal to the plane of the substrate luminescence occurs over a broad wavelength range, as is typical of ta-C:H. Visually this luminescence is white, while the color of the luminescence in the plane of the substrate depends on the film thickness. A film with a variable thickness yields radiation with a color that varies from turquoise to red. This monochromatization effect in a film/substrate system is observed for the first time.
