Electron paramagnetic resonance of organic and inorganic centers in gamma-irradiated natural sepiolite minerals
Koseoglu, Rahmi; Koksal, Fevzi; Akkurt, Mehmet; Ciftci, Emin (Walter De Gruyter Gmbh, 2006)Natural sepiolite minerals and their gamma-irradiated forms were investigated by electron paramagnetic resonance (EPR) at room temperature and at 113 K. The EPR signals in powders of natural sepiolite were observed due to ... -
EPR Spectra of Some Cu2+-Doped Metal Carbonates and Disorder Phase Transition in K3H(CO3)(2)
Demir, Dilek; Koksal, Fevzi; Kazak, Canan; Koseoglu, Rahmi (Verlag Z Naturforsch, 2009)Cu2+-doped K3H(CO3)(2), Rb2CO3, and Rb2KH(CO3)(2) single crystals were investigated by electron paramagnetic resonance (EPR) spectroscopy. The EPR spectrum of K3H(CO3)(2) indicates two different sites for Cu2+ at room and ... -
Phase transition in Cu2+-doped RbH2 PO4 as observed by EPR
Demir, Dilek; Koksal, Fevzi; Koseoglu, Rahmi (Taylor & Francis Ltd, 2009)The electron paramagnetic resonance (EPR) spectra of Cu2+-doped RbH2 PO4 at elevated temperatures indicate a phase transition at 358K. The EPR-silent state at this temperature is attributed to a so-called polymeric phase ...
