On thermal regime of nanoparticles in synthesis flame

2021 
Abstract Flame Synthesis conditions significantly affect nanoparticles properties. Understanding thermal regime in flames can be very useful for tuning nanoparticles with specific properties. In this work, information on thermal status is obtained through the analysis of light emission from nanoparticles during synthesis and under an external laser irradiation. We focus on the dependence of the particle temperature on laser fluence as reported in our previous work. We discuss temperature plateau observed in the low laser fluence regime as attributed to non-isothermality, that means the local coexistence of partially solidified particles at melting point and much hotter particles in a flame spray.
