Unravelling the UV luminescence of Bi-doped LiYGeO<sub>4</sub>: a journey from first principles to temperature-dependent photoluminescence
The study on Bi-doped LiYGeO 4 PersL reveals a ∼6.05 eV direct bandgap, supported by hybrid DFT calculations. Li loss during synthesis was confirmed by elemental analysis. Excitation to the MMCT enables UV PersL (peaked @ 358 nm) for up to 7 hours.
