Photostability of Fiber-Optic Photoacoustic Transducer Based on Silver Nanoparticle Layer

Abstract

The work is devoted to the experimental study of the microstructural properties of nanostructures before and after of the pulsed laser irradiation of the silver nanoparticle layer within the fiber-optic photoacoustic transducer prototype. The reaction of such transducer prototype on equivalent exposition of ~800 J/cm² is studied with atomic force microscopy and X-ray structural analysis. High photostability of nanostructure is demonstrated, degradation of nanostructures within the fiber-optic photoacoustic transducer prototype has not been observed. This allows such type of photoacoustic transducer to be used as part of a new generation of technical diagnostics systems.
