An enhancing factor : The enhancement of the electric properties of a dye molecule (IR26) by indium–tin oxide nanoparticles (ITO NPs, see picture) has been shown by measuring the near‐infrared two‐photon‐excited transient absorption spectra. The dye molecule was excited much more efficiently in the presence of an ITO NP layer.
