Investigation of photoinduced nucleation and growth of silver nanoparticles
Résumé
The influence of electromagnetic radiation with maxima wavelengths of 455, 520 and 630 nm on silver nanoparticles growth was investigated. The corresponding possibility of the plasmon resonance spectrum reconstruction in the visible range is shown. Investigations of the radiation frequency influence on the shape and size of the particles both at the stages of growth and at post-synthetic processing have been carried out. The possibility of transformation of spherical particles with a diameter of 20 nm into triangular shaped objects with a triangle edge length of 60–90 nm is shown. To study the optical characteristics of silver particles transmission spectroscopy was used as the primary diagnostic technique. The results of photometric measurements are in agreement with the data of scanning electron microscopy, which shows the transformation of the particles shape as a result of electromagnetic radiation.
