Journal ArticleDOI
The PrAlO3−Pr2O3 Eutectic, its Microstructure, Instability, and Luminescent Properties
D.A. Pawlak,Katarzyna Kolodziejak,Ryszard Diduszko,Krzysztof Rozniatowski,M. Kaczkan,Michal Malinowski,J. Kisielewski,Tadeusz Lukasiewicz +7 more
TL;DR: The growth of the eutectic by the micro-pulling down method is presented in this paper, where luminescence spectra are presented for both the PrAlO3−Pr2O3 and the new phase generated by exposure to air.
Journal ArticleDOI
XPS spectroscopy, structural, magnetic and dielectric investigations of CaGdAlO4 and Yb:CaGdAlO4 single crystals
Ewa Talik,J. Kisielewski,Paweł Zajdel,A. Guzik,E. Wierzbicka,Antoni Kania,Joachim Kusz,Seweryn Miga,M. Szubka +8 more
TL;DR: In this paper, the Czochralski method was used to grow CaGdAlO4 (CGA) single crystals, undoped and doped nominally with 8% at.
Journal ArticleDOI
Excited State Absorption and Thermoluminescence in Ce and Mg Doped Yttrium Aluminum Garnet
Krzysztof Wiśniewski,Cz. Koepke,Andrzej J. Wojtowicz,Winicjusz Drozdowski,Marek Grinberg,Slawomir Maksymilian Kaczmarek,J. Kisielewski +6 more
TL;DR: In this paper, the authors report preliminary results of optical studies on Y3 Al5012 (YAG) crystals codoped with Ce and Mg. They demonstrate that although the basic features introduced to the YAG host by the Ce-doping remain intact, the Mg-codoping imposes some significant changes on other properties of the material.
Journal ArticleDOI
Magnetic phases in Pt/Co/Pt films induced by single and multiple femtosecond laser pulses
TL;DR: In this article, an irreversible structural modification was introduced, which resulted in the creation of numerous pulse fluence-dependent magnetic phases, which exhibited a submicrometer domain structure.
Proceedings ArticleDOI
Changes in optical properties of YAG:Ce single crystals due to codoping and ionizing radiation treatment
Slawomir Maksymilian Kaczmarek,Andrzej J. Wojtowicz,Winicjusz Drozdowski,Czeslaw Koepke,K. Wisniewski,J. Kisielewski,Ryszard Jablonski,Marek Grinberg,J. Barzowska,Benedykt Kukliński,Georg Zimmerer,Z. Moroz,Henryk Rzewuski +12 more
TL;DR: In this paper, the ESR and ESA spectra of YAG:Ce crystals codoped with Mg2+ ions and subjected to various treatments have been measured and the variations induced by irradiations in gamma and proton beams, and by thermal annealings under oxidation and reduction conditions point to large variations of the cerium ion valency.
