Abstract
An analysis of the absorption and luminescence spectra of a Y2SiO5:Pr3 + crystal has revealed the existence of two Pr3+ optical centers assoc iated with the presence of impurity ions at nonequivalent cation sites . It is found that energy is transported nonradiatively between the no nequivalent Pr3+ optical centers. and a preliminary analysis of the tr ansport mechanism is carried out.
