Luminescent spectroscopy of Pr3+ ions in some phosphates, borates and silicates using x-ray synchrotron radiation from VEPP-3 storage ring.

This paper reports the spectroscopic properties of praseodymium-doped phosphates, borates and silicates. Polycrystalline samples of Pr3+-doped KLuP2O7, Li6Y(BO3)3, LiY6O5(BO3)3, LiSrPO4, Sr9Sc(PO4)7, K3Lu(PO4)2, K3LuSi2O7 were synthesized using a solid state reaction. Spectra of X-ray excited luminescence and its decay kinetics were measured. Studied samples demonstrate interconfigurational 5d-4f, intraconfigurational 4f-4f transitions and defect-related luminescence. Comparative analysis of spectroscopic properties and application perspectives is presented. [ABSTRACT FROM AUTHOR]
