Near-field scanning optical microscopy (NSOM) plays a key role in achieving optical resolution beyond the so-called diffraction limit and studying the properties of the plasmonic materials. The present report reviews the principle of near-field scanning optical microscopy and its different modes of operation. In addition, NSOM is extensively utilized to study the plasmonic properties of metals, graphene, and heavily doped semiconductors. The applications of NSOM in plasmonic materials is also reviewed. The advantage of NSOM in generating surface plasmon polaritons is especially emphasized. © Anita Publications. All rights reserved. doi:10.54955/AJP.33.1-2.2024.39-45.
