DFT and semi-empirical analyses of Cr-3(+) and Fe3+ impurity centers in Cs2NaYF6: Microscopic insight into structural properties

Erbahar, Doğan; Emül, Yakup; Açıkgöz, Muhammed (Elsevier, 2019)

A detailed microscopic study of the local geometry was performed for the cation sites in fluoroelpasolite Cs2NaYF6 crystal doped with 3d ions (Cr3+ and Fe3+). Electronic structure of pure, Crdoped and Fe-doped Cs2NaYF6 has ...
Microscopic insight into electronic and structural properties of Cr3+ and Fe3+ impurities in Cs2NaAlF6 via DFT and SPM analyses

Erbahar, Doğan; Emül, Yakup; Açıkgöz, Muhammed (Elsevier, 2019)

Allowing high transition metal (TM) ions doping concentrations makes the fluoroelpasolite crystals Cs2NaMF6 (M=Al, Ga) quite interesting in various laser applications. In this study, we explored the influence of the dopant ...
