Voltage‐Modulated Untwist Deformations and Multispectral Optical Effects from Ion Intercalation into Chiral Ceramic Nanoparticles (Adv. Mater. 16/2023)

Chiral Ceramic Nanoparticles In article number 2206956, Hendrik Heinz, Nicholas A. Kotov, and co-workers describe how the chirality of V2O3 nanoparticles strongly changes when they intercalate Zn2+ ions, generating strong modulation f polarization rotation from the ultraviolet to infrared range. High g-factors, synthetic simplicity, and environmental robustness of self-assembled composite films from chiral V2O3 nanoparticles provide a versatile platform for photonic devices.
