Optical properties of Ce3+ doped ABO3 perovskites (A=La, Gd, Y and B=Al, Ga, Sc)

The optical properties of two series of perovskites (first: LaAlO3, GdAlO3 and YAlO3 and second: LaAlO3, LaGaO3 and LaScO3) doped with Ce3+ (1%) ions were measured. The collected data allows us to determine and estimate values of centroid shift (εc) and crystal field splitting (εcfs). The influence of ionic radii, electronegativity of cations and distortion of structure on those parameters are shown. - Highlights: ► Nanocrystallite ABO3 (where A=La, Gd, Y and B=Al, Ga, Sc) perovskites were synthesized. ► Spectroscopic properties of Ce3+ in ABO3 (where A=La, Gd, Y and B=Al, Ga, Sc) were determined. ► Centroid shift in function of average distance between Ce3+ and ligands was found. ► Crystal field splitting of Ce3+ levels in ABO3 (where A=La, Gd, Y and B=Al, Ga, Sc) was found.
