ABSTRACT:
A method of forming a phosphor film includes: providing phosphor powder having a particle size of less than 5 μm; subjecting the phosphor powder to vibration so as to form an aerosol containing phosphor powder dispersed therein; and injecting the aerosol into a substrate at a high speed using carrier gas, such that the phosphor powder is impact-solidified on the substrate repeatedly moving at a predetermined speed.
