Abstract:
Phosphor films, methods of forming the phosphor films, and methods of coating a phosphor layer on light-emitting chips are disclosed. The phosphor film includes: a base film; a phosphor layer that is formed on the base film and comprises an incompletely cured resin material and phosphor particles mixed with the incompletely cured resin material; and a cover film that is formed on the phosphor layer and protects the phosphor layer.
