Combating fogging with selective sunlight nano-absorbers

An Author Correction to this article was published on 01 February 2023

This article has been updated

A nanoscopically thin gold coating at the optical percolation threshold was fabricated using scalable methods. Despite its extreme thinness, the film absorbs about 30% of the solar radiation while being transparent. The resulting photoinduced heating prevents or mitigates fogging on transparent surfaces.
