Effect of the functionalization (CO-tips vs. bare-metal tips) and substrate on the photon maps and spectra of the dynamic ZnPc molecules. The two upper rows show data taken above ZnPc on the 3ML-NaCl/Au(111). The two bottom rows are results obtained above ZnPc on 3ML-NaCl/Ag(111). STM images at constant current (CC), constant height (CH), STM-induced luminescence (STML) maps at constant height measured with metal and CO tips are presented for comparison. The numbered spectra shown on the right-hand side column have been taken at the positions marked in the CC STM images. All image sizes are 2.2 x 2.2 nm2, tunneling current setpoints for CC images were 10 pA and 1 pA on Au and Ag substrate, respectively.
