Correction to: Journal of Sol-Gel Science and Technology (2022) 12:1–6 https://doi.org/10.1007/s10971-022-05836-7

The original version of this article unfortunately contained a mistake. The 5th sentence under 2nd paragraph of “Introduction” section should be changed from “For instance, Katagiri et al. have reported thick films with a thickness up to 8 μm by electrophoretic deposition and subsequent thermal softening of phenyl-silsesquioxane, but the transmittance of these films was <1% in a wide visible range [19]”. to “For instance Katagiri et al. have reported transparent films with a thickness up to 3 μm by electrophoretic deposition and subsequent thermal softening of phenylsilsesquioxane [19]”.

The original article has been corrected.
