Key Points

This work aims to investigate a method for tuning defect properties in ceria nanoparticles using electron beam irradiation.
Used high-dose MeV beam irradiation to modify defect-related properties in nanoparticles.
Synthesized oleate/oleylamine-stabilized ceria nanoparticles in the size range of 2–3 nm.
Conducted experiments under controlled thermal conditions to ensure reproducibility.
Enhanced defect properties were achieved through post-synthetic electron beam irradiation.
Demonstrated significant modification of nanoparticle characteristics without additional dopants.

Implication

Explores defect properties in ceria nanoparticles, suggesting new engineering methods for nanoscale materials.

Abstract

This work explores high-dose MeV beam irradiation as a dopant-free, post-synthetic route to tune defect-related properties in 2–3 nm colloidal CeO 2 nanoparticles. Oleate/oleylamine-stabilised nanoceria were reproducibly prepared via degassing-controlled thermal...
