Tailoring oxide nanoparticle exsolution in La0.5Ba0.5-yCo1-xFexO3-δ
PublicationWe show that oxide nanoparticles (NPs) exsolve on La0.5Ba0.5-yCo1-xFexO3-δ (x = 0-1, y = 0 or 0.01) in oxidizing conditions. The phenomenon occurs only in Co-containing materials and depends on pO2 and pH2O pressures. Under dry conditions, the smallest NPs average about 30 nm, with 200-300 NPs/µm2 at pO2=5×10-5 atm. For pO2=1 atm, NP size increases to 100-200 nm, and population drops to a few to about 20 NPs/µm2 depending on A-site...
