The crystal field splitting decreases when more N3− versus O2− is coordinated to Ce3+, which is ascribed to the higher formal charge of nitrogen versus oxygen (van Krevel et al. 1998). The Stokes shift becomes smaller in the series Y5(SiO4)3N>Y4Si2O7N2>YSiO2N>Y2Si3O3N4, ...
The formal charge of an atom present in a compound is determined by combining three factors: (1) number of valence electrons of the atom, (2) number of covalent bonds attached to the atom, and (3) number of electrons in its lone pairs....
