A method of enhancing the photo luminescent film sandwich structure and a preparation method of the fluorescence intensity of

The present invention relates to a method for preparing reinforced sandwich structure and the fluorescence intensity of the photoluminescence emission film, the sandwich structure is a transparent dielectric micron beads of tightly plated film formed on the surface of the substrate the light emitting - light emitting film - single tessellate sandwich bead array; m is used for a dielectric pellet in optically stimulated luminescence emission wavelength of excitation light and fluorescence having higher transmittance; using fluorescence enhancement media - micron transparent dielectric pellet price low for industrial scale applications; used microns transparent dielectric pellet no oxidation in an air environment, long-term stability enhanced light emitting thin film photoluminescence light emission intensity; used microns transparent dielectric beads light emitting film and does not require the substrate, the substrate may be a metal or non-metal, effectively extends the application range of the light emitting film photoluminescence emission enhancement technique.
