THIN FILM WAVELENGTH CONVERTERS AND METHODS FOR MAKING THE SAME

摘要

Thin film wavelength converters and methods for making the same are disclosed. In some embodiments, the thin film converters include a first thin film layer of first wavelength conversion material, a conductive layer, and a second thin film layer of a second wavelength conversion material. In one embodiment, a photoresist mask is applied to the conductive layer to form a pattern of by which the second wavelength conversion material may be applied by electrophoretic deposition to the exposed regions of the surface of the conductive layer.

主权项

1. A thin film wavelength converter, comprising:
a substrate; a first thin film layer, said first thin film layer comprising at least one first wavelength conversion material; a conductive layer; and a second thin film layer deposited on said conductive layer, said second thin film layer comprising at least one second wavelength conversion material; wherein: said first thin film layer is configured to convert incident primary light from a light source in a first wavelength range to secondary light in a second wavelength range; and said second thin film layer is configured to convert at least one of said primary light and said secondary light to tertiary light in a third wavelength range, said second wavelength range being different from said third wavelength range.
