Název v původním jazyce

The development of reference probe system for tip-enhanced Raman spectroscopy

Popis výsledku v původním jazyce

The tip-enhanced Raman spectroscopy (TERS) is a modern analytical technique with an outstanding spatial resolution and chemical sensitivity. These parameters mainly depend on the structural integrity and chemical purity of employed plasmonic scanning probe tips. Usually, each tip is tested before TERS measurements using commercially available reference samples. However, their price and relatively short expiration date must be considered when planning a research budget. We developed a procedure to produce self-made reference probe samples for testing TERS tips using copper(II) phthalocyanine on a Au nanolayer, which is prepared by thermal vacuum evaporation of Au on a Si wafer. Our results show that the prepared system enables repeated detection of well-resolved TERS spectra. The collected TERS spectra and spectral maps exhibit some degree of variability, which may be due to various photo-induced processes, and it must be considered while performing TERS measurements.
