Photo‐Switchable FRET‐Enabled Flexible Luminescent Films for Multilevel Optical Security
Carbon Energy, EarlyView.A light‐gated FRET composite integrates a Tb‐Phen donor and a spiropyran acceptor in a polyurethane matrix. Under 365 nm light, spiropyran is transformed into merocyanine, creating spectral overlap with Tb3+ emission and activating energy transfer. Visible light reverses the switch, restoring green emission and enabling reversible multilevel optical ...
