Novel Wide Viewing Optical Films Based on Double-Shell Layered Nanoparticles with Gradient Refractive Index Surface |
| 초록 |
The essential improvements in the performance of light-diffusing materials for wide viewing angles in potential optoelectronic applications have attracted considerable attention. In this study, a simple and unprecedented strategy is proposed to provide exceptional light scattering performance and high optical transparency for optical thin films using hierarchical double-shell nanoparticles possessing a refractive index gradient on the nanoparticle surface. An ultraviolet-light-cured optical film with an extremely low content of double-shell nanoparticles exhibits efficient light scattering characteristics while maintaining high optical transparency. The hierarchical SiO2/TiO2/poly(methyl methacrylate) double-shell layered nanoparticles induce enhanced light scattering properties by their nanolayered gradient refractive index structure. This proposed technique provides a scalable yet effective, facile approach to improve the viewing angle performances of optoelectronic devices. |
