Abstract:
1. A package, at least comprising: a light source; and a molding compound, encapsulating the light source, and the light source disposed in a bottom portion of the molding compound, the molding compound comprising: a solid organic polymer, polymerized from an organic matrix; and a plurality of surface modified inorganic nanoparticles with functional groups or oligomers with functional groups, distributed in the solid organic polymer, and the surface modified inorganic nanoparticles with functional groups or oligomers with functional groups being distributed from the bottom portion to a top portion of the molding compound so that the molding compound presents a gradient refraction index, wherein the surface modified inorganic nanoparticles with functional groups or oligomers with functional groups have higher polymerization rate than the organic matrix under a gradient-generating step.
