Final Report Abstract

During this project we were able to conduct significant studies on the thermal activation of dye decomposition in proximity of laser pulse heated gold nanoparticles in colloidal solution. However, we found that the decomposition of dyes on the surface of gold particles was extremely difficult to interpret due the several effects which were unforeseen in the original proposal. Hence, a deduction of real temperature profiles in the proximity of the heated nanoparticles was a challenging task. We therefore additionally pursued an additional route (which was not proposed in the original proposal) to answer exactly the question of heat distribution around laser pulsed heated gold nanoparticles. Namely we grew relatively thick metal organic framework (MOF) shells around gold nanoparticles and irradiated the composite particle with a strong pulsed laser which was in resonance only with the LSPR of the gold particle but which was not absorbed by the MOF. In the vicinity of the gold particles the MOF was decomposed and the size and shape the voids generated in the MOF particles allowed us to draw conclusions on the heat dissipation around strongly heated nanoparticles. Furthermore, several other studies concerning the synthesis and plasmonic behavior of plasmonic nanoparticles were also conducted in the framework of this project. The developed method for investigating the heat transport in the vicinity of nanoparticles and composite nanoparticles using MOF shells is of particular interest to many scientists, since it can be easily transferred to any nanoparticle or heteronanoparticle.
