University Of Central Florida Researchers’ Smartphone Screen Modeled After Moth Eyes.

NBC News (6/26, Yiu) “Inside Science” reports University of Central Florida researchers published a paper in the journal Optica this week describing an anti-reflection film optimized “specifically for smartphone screens, and they also provide a model that other researchers can use to optimize their own films.” NBC News says engineers and materials scientists have often modeled their anti-reflection films after moths’ eyes, which feature surface-level nanoscale structures that minimize light reflection. Likewise, the UCF team led by Shin-Tson Wu deposited a solution of nanoscale silicon oxide spheres measuring about 100 nanometers across onto a surface that was then dimpled to create “the nanoscale structure that mimics what moths have on the surface of their eyes.” Stanford University material scientist Dietmar Knipp, who was not involved in the research, explained that “imprinting is usually a good choice,” but Wu conceded the process loosened some of the nanoparticles, rendering the dimpling stamp unusable.
