Abstract

We have used the near-field scanning optical microscope (NSOM) to study the inhomogeneity as well as initiate photochemical processes in conjugated polymer films. A simple transmission-mode NSOM is constructed for these studies. A low noise, large area Si photo-detector is mounted directly between the PZT scanning stage and the sample. This method provides a simple way to covert the commercial AFM/STM scanning stage to a near-field optical microscope.
