| dc.description.abstractEn | The luminescence of Yb3+ in the oxyborate Li2Lu5O4(BO3)3 is reported. At low temperature, in addition to the usual ytterbium infrared emission, this phosphor presents an emission in the ultraviolet (lmax = 345 nm) which corresponds to the transition from the charge transfer state (O–Yb) to the 4f levels of Yb3+. The temperature quenching Tq50% is equal to 120 K. The infrared emission studied at room temperature is located between 950 and 1100 nm. Europium emission quenching in the Li2Yb5O4(BO3)3 phase is related to Eu→Yb transfer by cross-relaxation. The reverse Yb→Eu transfer by cooperative sensitization is highlighted in the codoped Li2Lu5O4(BO3)3 compound. | |
