Two new materials based upon layered double hydroxides with nickel and cobalt in the
brucite-like layer with and without an anionic surfactant dodecylsulfonate (DS) have been …

This work is aimed at clarifying the changes on optical spectra of Cr3+ impurities due to
either a host lattice variation or a hydrostatic pressure, which can hardly be understood by …

Four new metallophosphonates with the chemical formulae M (H2O) PO3-S2C12H7 (M= Cu,
Zn) and M (H2O) 2 (PO2OH-S2C12H7) 2 (M= Mn, Co) were synthesized using a …

Although the lattice constants of K Mg F 3 (normal cubic perovskite structure) and Ba Li F 3
(inverted perovskite) materials differ only by 0.3%, there is a significant difference between …

Although in LiBaF 3: Mn 2+ the impurity replaces Li+ thus forming octahedral MnF 6 4− units
the experimental hyperfine and anisotropic superhyperfine constants and the energies of dd …

The de-excitation mechanisms from the 4T 2 (4F) level for a promising new vibronic laser
material, BaLiF3: Co2+ (emission centered at 1588 nm, FWHM= 426 nm), are reported. At …

Abstract Highly transparent KAlF4 and Na5Al3F14 fluoride bulk single crystals in size of≈ Ф
50 mm× 10 mm are successfully grown for the first time by a modified Bridgman method. The …

This paper describes a computational study of the mixed metal fluorides LiCaAlF 6 and
LiSrAlF 6, doped with divalent (Pb 2+, Co 2+ and Ni 2+), trivalent (Cr 3+, Fe 3+ and Y 3+) …

The core scientific question of this thesis is the evaluation of device-related (100)-Ga 2 O 3
Czochralski (Cz) grown bulk crystals and metal-organic vapor phase epitaxy (MOVPE) …

The growth of KZnF 3 single crystals doped with∼ 0.2 mol% cobalt ions by an improved
Bridgman method is reported. The crystal structure characterized by the x-ray diffraction …
