Writing in a Polyaniline Film with Laser Beam and Stability of the Record: A Raman Spectroscopy Study

Figure 4

Raman spectra of a line burnt to the PANI-S film on gold with a 0.2 W 1064 nm laser line at low speed, obtained with the 633 nm excitation line at a marked time after burning. The samples were stored at room temperature in air.
