Abstract
A device construct for lighting and display applications is fabricated from a substrate, a deposited phosphor layer over the substrate, and a layer of thermal and electrically-conductive luminescent material over the deposited layer. The layer of thermal and electrically-conductive luminescent material is a thin film that conforms to the morphology of the phosphor layer. The device is fabricated by providing a substrate, depositing a thin layer of phosphor powder on the substrate by any technique, and coating the phosphor layer with a layer of thermal and electrically-conductive luminescent material by atomic layer deposition.
