A printed layer of yellow phosphors on a surface‐roughened glass substrate for white light‐emitting diodes is presented. The layer of well‐dispersed phosphors in a glass matrix is broadly applicable for a large scale planar lighting system. When combined with a nanoscale surface‐roughening technique of the substrate, enhanced luminescence efficiency is achieved as a result of effective light extraction. Y. S. Cho and co‐workers describe this simple processing methodology with experimental evidences on page 1081.
