Defect and spectroscopy properties of Eu-doped LiMgPO4 phosphors

Modulating A site compositions of europium(iii)-doped double-perovskite niobate phosphors

“…, occupancy and local structural distortion) might produce different lattice defects like Schottky and Frenkel defects that can affect the energy level distribution and the ability to bind carriers, thereby resulting in different luminescence behaviors. 45–50…”

“…In this respect, even though the doped rareearth ions (here is Eu 3+ ion) are the same, the phase or different microstructure environments (e.g., occupancy and local structural distortion) might produce different lattice defects like Schottky and Frenkel defects that can affect the energy level distribution and the ability to bind carriers, thereby resulting in different luminescence behaviors. [45][46][47][48][49][50] Fig. 3( j-l) shows the PL emission spectra of the CINO: xEu 3+ , SINO:yEu 3+ , and BINO:zEu 3+ phosphors.…”

Unlocking the effect of Li and Ce ions on the thermoluminescence and optically stimulated luminescence signals of the MgB4O7 compound

“…19 This method has been very useful for calculating point defects (intrinsic and extrinsic) in atomistic simulations and has presented successful results in studying solid-state materials. [20][21][22][23][24] In this method, the crystal lattice is divided into two spherical regions (I and II), and the point defect is placed in the centre of these regions. The inner region I is the portion of the crystal lattice located around the defect, allowing the explicit relaxation of all the ion positions under the action of a force field.…”
