Submicrometer‐sized (830 ± 40 nm) mesoporous TiO2 beads are used to form a scattering layer on top of a transparent, 6‐µm‐thick, nanocrystalline TiO2 film. According to the Mie theory, the large beads scatter light in the region of 600–800 nm. In addition, the mesoporous structure offers a high surface area, 89.1 m2 g−1, which allows high dye loading. The dual functions of light scattering and electrode...
Porous polymer films that can be employed for broadband and omnidirectional antireflection coatings are successfully shown. These films form a gradient‐refractive‐index structure and are achieved by spin‐coating the solution of a polystyrene‐block‐poly(methyl methacrylate) (PS‐b‐PMMA)/PMMA blend onto an octadecyltrichlorosilane (OTS)‐modified glass substrate. Thus, a gradient distribution of PMMA...
