Leite and co-workers (article number 2200159) demonstrate thin-film-based color filters using Mg and MgO, both biodegradable materials. Color filters, earth-abundant materials, magnesium, structural colors, transient photonics A transient color response is attained by etching the Mg-containing layers with water, which reveals the hue of a bottom Fabry-Pérot cavity structure.
