DOI: 10.1021/acsami.9b10236
Abstract: We demonstrate structural colors produced by a simple, inexpensive, and non-toxic electrodeposition process. Asymmetric metal-dielectric-metal multilayered structures were achieved by sequential electrodeposition of smooth gold, thin cuprous oxide, and finally thin Au on conductive substrates,… read more here.
