Application of epi-luminescence microscopy technique for visualization and control of luminophore distribution on a developed surface
A method based on the epi-luminescence microscopy is proposed for the test substance spreading area estimation, as well as the uniformity of its distribution on a substrate with a developed nanostructured surface. This method can be used to calculate the test substance SERS-signal enhancement adsorbed on a complex developed surface where standard methods for the amount of a substance estimation are inapplicable. For a colloidal solution of semiconductor quantum dots adsorbed on the surface of a track-etched membrane with silver dendritic nanostructures, a change in the surface wettability was found depending on the number and size of dendrites on it.
