Band Gap Engineering and Trap Depths of Intrinsic Point Defects in RAlO3 (R = Y, La, Gd, Yb, Lu) Perovskites
(American Chemical Society, 2021)The possibility of band gap engineering (BGE) in RAlO3(R = Y, La, Gd, Yb, Lu) perovskites in the context of trap depths of intrinsic point defects was investigated comprehensively using experimental and theoretical approaches. ... -
Effect of Ga content on luminescence and defects formation processes in Gd3(Ga,Al)5O12:Ce single crystals
(Elsevier B.V., 2018)Luminescence characteristics of Ce3+ - doped Gd3GaxAl5-xO12 single crystals with different Ga contents (x = 1, 2, 3, 4, 5) are studied in the 9–500 K temperature range. The spectra of the afterglow, photoluminescence, ... -
Structural and electronic properties of β-NaYF4 and β-NaYF4:Ce3+
(Elsevier B.V., 2020)In this work, the density functional theory approach with linear combination of atomic orbitals (LCAO) as implemented in the CRYSTAL17 computer code is applied to hexagonal β-NaYF4, located in three possible space groups ...
