Fig. 4: AFM-IR characterization of the POM-ZnPc layer.
From: Single polyoxometalate-based nanoclusters characterized by infrared absorption nanospectroscopy
a AFM-IR topographic image of the POM-ZnPc//HOPG sample; b AFM-IR infrared image of the POM-ZnPc//HOPG sample recorded at 950 cm−1; c AFM-IR infrared image of the POM-ZnPc//HOPG sample recorded at 1645 cm−1; d height profile (left) and IR spectrum (right) of a mixed aggregate (“big” nano-object, marked by purple line in the topographic image); e height profile (left) and IR spectrum (right) of a pure ZnPc aggregate (flat nano-object, marked by red line in the topographic image). The pure POM-pyr aggregate is marked by a white arrow on the three images.
