Influence of high pressure on Ce3+ luminescence in LuAlO3 and YAlO3 single crystals and single crystalline layers
Lev Ivan Bulyk, Ajeesh Kumar Somakumar, Hanka Przybylińska +11
Results of spectroscopic studies at ambient and high pressures of a LuAlO3:Ce3+ (LuAP:Ce) single crystalline film (SCF) as well as LuAP:Ce and YAlO3:Ce (YAP:Ce) single crystals are…
Transition metal ions in ZnO: effects of intrashell Coulomb repulsion on electronic properties
A. Ciechan, P. Bogusławski
Electronic structure of the transition metal (TM) dopants in ZnO is calculated by first principles approach. Analysis of the results is focused on the properties determined by the…
Metastability of Mn in ZnO driven by strong (Mn) intrashell Coulomb repulsion: experiment and theory
A. Ciechan, H. Przybylińska, P. Bogusławski +5
Depopulation of the Mn state in ZnO:Mn upon illumination, monitored by quenching of the Mn EPR signal intensity, was observed at temperatures below 80~K. Mn ph…
Fe dopant in ZnO: 2+ vs 3+ valency and ion-carrier s,p-d exchange interaction
J. Papierska, A. Ciechan, P. Bogusławski +16
Dopants of transition metal ions in II-VI semiconductors exhibit native 2+ valency. Despite this, 3+ or mixed 3+/2+ valency of iron ions in ZnO was reported previously. Several con…
Lattice parameters and stability of the spinel compounds in relation to the ionic radii and electronegativities of constituting chemical elements
M. G. Brik, A. Suchocki, A. Kamińska
A thorough consideration of the relation between the lattice parameters of 185 binary and ternary spinel compounds, on one side, and ionic radii and electronegativities of the cons…
Ag and N acceptors in ZnO: ab initio study of acceptor pairing, doping efficiency, and the role of hydrogen
O. Volnianska, P. Boguslawski, E. Kaminska
Efficiency of ZnO doping with Ag and N shallow acceptors, which substitute respectively cations and anions, was investigated. First principles calculations indicate a strong tenden…
Time-resolved spectroscopy of exciton states in single crystals, single crystalline films and powders of YAlO_3 and YAlO_3:Ce
V. Babin, L. Grigorjeva, I. Kondakova +6
Luminescence characteristics of single crystals (SC), single crystalline films (SCF), powders and ceramics of YAlO_3 and YAlO_3:Ce have been studied at 4.2-300 K under photoexcitat…
