Pulsed laser ablation (PLA) was used to prepare nanoparticles of barium titanate (BaTiO 3 ). PLA using a titanium‐rich Ba–Ti–O ceramic target in oxygen ambience at 400 Pa and following online annealing at 1073 K enabled the production of BaTiO 3 nanoparticles (BTNPs) with a perovskite structure having nearly stoichiometric composition. These nanoparticles were directly introduced into a differential mobility analyzer for size classification, leading to the production of monodispersed and nonagglomerated BTNPs with an average particle size of 13.5 nm. The size distribution of the size‐classified BTNPs was found to be reasonably narrow with a geometric standard deviation of 1.07.
