摘要：

The luminescence of Eu3+ in two monazite-type orthophosphates: La0.98Eu0.02PO4 and EuPO4 is investigated by site-selective time-resolved spectroscopy. Informations on the nature of perturbed sites in the doped phosphate and on the localization of the europiums on normal lanthanum sites or on perturbed sites are discussed considering the crystal held parameters and the analysis of the site-to-site energy transfers. Vibronic satellites are observed in both the doped and the neat compounds and assigned to the coupling between the D-5(0) --> F-5(0,1,2) transitions and the localized vibration modes of the (PO4)(3-) groups.
