Photoluminescence properties of Eu3+ in Y(PO3)3 under VUV excitation

The photoluminescence properties of Y1−x(PO3)3:xEu3+ (0

Research highlights► The (PO3)33−groups and CT bands of O2−-Y3+ can efficiently absorb the VUV excited energy. ► The absorbed energy by the host matrix can be efficiently transferred to Eu3+ under VUV excitation. ► The excitation and energy transfer approach is different under 147 nm and 172 nm excitation.
