How exciting! Upon excitation of Rhodamine B with visible light in magnetic Co nanocrystal–Rhodamine B nanocomposites, electron transfer from the nanocrystal to the dye is evidenced as well as an increase in magnetisation (see picture), affording a new access to photomodulation of the magnetic properties of nanocrystal assemblies.
