Semiconductor light emitting devices are fabricated by placing a suspension (120) comprising particles (122) suspended in solvent (124) on at least a portion of a light emitting surface (110a) of a semiconductor light emitting element (110), and evaporating at least some of the solvent to cause the particles to deposit on at least a portion of the light emitting surface. A coating including the particles is thereby formed on at least a portion of the light emitting surface.
