Abstract
Semiconductor light emitting devices are fabricated by placing a suspension including phosphor particles suspended in solvent on at least a portion of a light emitting surface of a semiconductor light emitting element, and evaporating at least some of the solvent to cause the phosphor particles to deposit on at least a portion of the light emitting surface. A coating including phosphor particles is thereby formed on at least a portion of the light emitting surface. Particles other than phosphor also may be coated and solutions wherein particles are dissolved in solvent also may be used.
