Abstract(in English) Recently, the need for optical materials with high refractive index and high transparency has increased markedly, especially in the fabrication of antirefiective coatings, microlens array of CCD, and optical encapsulants of LED which are vital components of advanced photonic devices. In this study, in an attempt to fabricate a high-n as well as a highly transparent polymer nanohybrid composite, a combination of a polymer matrix, NPs, and surface coupling agent was tailored systematically. We developed a novel and versatile hybridizing process for further increasing the n value of the nanohybrid composites. A highly transparent (transmittance ≈ 93% at 460nm) polymer nanohybrid composite across the entire visible range with the highest refractive index of n(594 nm) ≈ 2 has been achieved for the first time.
