Autor: L. Beaury, A. El Jazouli, J. Derouet, R. Olazcuaga, G. Le Flem, A.El Bouari, Pierre Porcher, J. M. Dance
Publikováno v: Journal of Solid State Chemistry. 143:230-238
The optical (energy level scheme) and magnetic properties (paramagnetic susceptibility as a function of the temperature and g values) of the polycrystalline Co 0.5 Ti 2 (PO 4 ) 3 were simultaneously reproduced by use of a crystal field theory involvi

Autor: M.C. Marco de Lucas, M. Moreno, J. M. Dance, Fernando Rodríguez, Alain Tressaud, J. Grannec
Publikováno v: Radiation Effects and Defects in Solids. 135:19-22
New elpasolites like A2KMF6 doped with Cr3+ have been investigated by means of optical and EPR techniques. It is shown that though the structural phase transition undergone by Rb2KGaF6 at T = 129 K is much stronger than that corresponding to Rb2KInF6

Electrochemical Preparation and Structural Characterization of La2NiO4+δ Phases (0 ≤ δ ≤ 0.25)
Autor: Alain Wattiaux, Michel Pouchard, Jean-Louis Soubeyroux, J.-C. Grenier, P. Hagenmuller, Alain Demourgues, J. M. Dance
Publikováno v: Journal of Solid State Chemistry. 105:458-468
Electrochemical oxidation in alkaline solution has been used to control and to extend the oxygen overstoichiometry of La 2 NiO 4+δ phases (0 ≤ δ ≤ 0.25). Chemical analysis has been carried out to determine the nickel (III) content and the relat

Luminescence of the new elpasolite Rb2KGaF6 doped with Cr3+
Autor: J. M. Dance, Fernando Rodríguez, Miguel Moreno, Alain Tressaud, C Marco de Lucas
Publikováno v: Journal of Luminescence. :553-557
Photoluminescence, lifetime, optical absorption and EPR measurements on Rb 2 KGaF 6 :Cr 3+ have been carried out in the 10–300 K temperature range. The emission spectrum at 10 K shows a very rich vibrational structure which can be mainly explained
