Light switches : UV irradiation induces Rhodamine B (RhB) aggregation into nanoparticles and changes RhB photoluminescent emissions from yellow to white light (see graphic). The UV‐induced changes are reversible. A novel approach to generate organic fluorescent nanoparticles and to prepare white‐light‐emitting fluorescent materials is demonstrated.
