Abstract

This paper summarizes time-resolved laser-induced incandescence (TiRe-LII) measurements on silver nanoparticles synthesized in solution and then aerosolized in Ar, N2, and CO2 using a pneumatic atomizer. The optical properties of molten silver are presented along with a peak temperature analysis. An attempt was made to recover both the silver nanoparticle size and thermal accommodation coefficient by calculating and regressing the experimental effective temperature from the measured incandescence with modeled data. The recovered values for the nanoparticle size were consistent with ex situ characterization but the TAC values could not obtained due to evaporation being the dominant form of heat transfer.
