Abstract: Composite hydrogel films for contact lenses and the methods of manufacturing are provided. The composite hydrogel films are formed by the following steps of: mixing a hydrogel precursor with nanospheres dispersed in a colloid; evaporating the solvent in the mixture; curing the hydrogel to form a composite hydrogel film having nanospheres arranged in amorphous arrays. The composite hydrogel films selectively reflect light in hazardous wavelengths.

Abstract: The present invention discloses a fluorescence enhancing gel-film and the manufacture method thereof. The aforementioned fluorescence enhancing gel-film comprises a frame-gel and a nano-scale spherical cavity structure. The frame-gel is in a form of a film. The nano-scale spherical cavity structure which is distributed in a periodic or non-periodic arrangement is disposed in the frame-gel. The fluorescence enhancing gel-film is able to improve the emitting performance and efficiency of a light emitting device significantly.
