Abstract
A thin-film phosphor layer can be formed by an improved deposition method involving: (1) forming a phosphor powder layer that is substantially uniformly-deposited on a substrate surface; and (2) forming a polymer binder layer to fill gaps among loosely packed phosphor particles, thereby forming a substantially continuous layer of thin film.
