Abstract
A correlation between the particle size and the lattice parameter has been established in nanocerium oxide particles ( 3 – 30 nm ) . The variation in the lattice parameter is attributed to the lattice strain induced by the introduction of Ce 3 + due to the formation of oxygen vacancies. Lattice strain was observed to decrease with an increase in the particle size. Ce 3 + ions concentration increased from 17% to 44% with the reduction in the particle size.Keywords
