Luminescence of Li6Y(BO3)3 doped with Pr3+ ions under x-ray, electron beam and ultraviolet excitation

Abstract

This paper reports the spectroscopic properties of praseodymium-doped lithium yttrium triple borates, Li6Y(BO3)3:Pr3+(1%). Emission and photoluminescence excitation spectra were measured at room temperature in the near IR and VIS-UV range. For this Pr3+- doped triple borates, the interconfigurational 4𝑓15𝑑→4𝑓2 transitions with nanosecond decay time were detected. Besides the intraconfigurational 4𝑓2→4𝑓2 transitions in visible and near IR regions were analyzed.
