Abstract: A phosphor composition is provided. The phosphor composition comprises a phosphor nucleus and a hydrophobic layer. The hydrophobic layer is bonded on a surface of the phosphor nucleus and consists of an organic compound with a hydrophobic functional group.

Abstract: A light source module includes a substrate, a first LED package and a second LED package. The first and second LED packages are disposed on the substrate. The first LED package includes a first blue LED chip and a first phosphor. The first blue LED chip emits light in the range of the wavelength for blue light. The first phosphor is used to convert the wavelength of a portion of the light emitted from the first blue LED chip. The second LED package includes a second blue LED chip and a second phosphor. The second blue LED chip emits light in the range of the wavelength for blue light. The second phosphor is used to convert the wavelength of a portion of the light emitted from the second blue LED chip. The wavelength associated with the second phosphor is greater than that associated with the first phosphor.

Abstract: An organic/inorganic hybrid composite proton exchange membrane is provided. The proton exchange membrane includes an inorganic material of about 0.5-30 parts by weight and an organic material of about 99.5-70 parts by weight per 100 parts by weight of the proton exchange membrane. A surface area of the inorganic material is about 50-3000 m2/g. The organic material includes a sulfonated polymer or a phosphoric acid doped polymer.

Abstract: A composite proton exchange membrane is made up of dispersed organized graphene in ion conducting polymer as a fuel barrier material. The composite proton exchange membrane includes an inorganic material of 0.001-10 wt % and an organic material of 99.999-90 wt %. The inorganic material is a graphene derivative with two-dimensional structure. The organic material includes a polymer material with sulfonic acid group.
