摘要：

The dependence of UF5 nanoparticle size distribution on growth time was investigated for various initial concentrations of UF5 monomers. UF5 nanoparticles prepared by photodissociation of UF6 in a mixed-flow reactor were allowed to pass through a plug-flow reactor (PFR), and their size distribution was measured by an in-situ size-monitoring system, namely a low-pressure differential mobility analyzer. By changing the length of the PFR, the growth time in the PFR was controlled from 0 to 30 s. An analysis using, Lee's coagulation model revealed that the growth mechanism of the UF5 nanoparticles involved a Brownian coagulation process and that the sticking probability of the nanoparticles was approximately unity.
