Abstract
In this work we report the spectroscopic observation of single organic molecules in solid-deposited matrices using a confocal microscope at liquid-helium temperature. The fluorescence microscopy allowed to study the spectroscopic properties of many single molecules in parallel Matrix isolation technique was adopted to produce a solid samples directly on the objective surface. From sequential images recorded at different excitation laser frequency the spectral line-widths of corresponding zero-phonon absorption lines could be obtained. For investigated compounds of interest at different matrices the line-widths have been measured. Spectral stability of single molecules has been investigated under excitation.
