Experimental results on the impact of factorization and technology independent mapping options on multilevel synthesis

Autor: G. Saucier, T. Besson, F. Gaume, K. Sakouti, P. Abouzeid, R. Roane

Publikováno v: Proceedings Euro ASIC '92.

Permanent research efforts are made on various factorization options (algebraic and boolean techniques, extensive use of don't care. . .). In parallel, similar efforts have been put on adequate factorization improvements or modifications (controlled

Photoionization process of rare earth impurity ions in some potential solid-state laser materials and in a system presenting a persistent spectral hole burning

Autor: Donald S. McClure, F. Gaume, Christian Pedrini, F. Rogemond

Publikováno v: Journal of the Less Common Metals. 112:103-107

Photoconductivity measurements have been carried out on doped single crystals Eu 2+ :CaF 2 , Ce 3+ :YAG and Sm 2+ :CaF 2 . It is shown that the strongly excited-state absorption occurring in the former two solid-state laser systems, and the spectral

Electronic structure and photoluminescence processes in Bi4Ge3O12 single crystal

Autor: F. Gaume-Mahn, Bernard Jacquier, J. Janin, Richard Moncorgé, Georges Boulon

Publikováno v: Journal of Luminescence. :467-472

Spectral experiments and decay time measurements from 4 to 400 K of Bi 4 Ge 3 O 12 single crystal show some appreciable changes with regard to those described for the activator centers Bi 3+ . We try to identify the nature of the absorbing centers as

Synthesis of new luminescent materials activated with divalent samarium

Autor: F. Gaume, J.C. Gacon, A. Gros

Publikováno v: Journal of Solid State Chemistry. 36:324-330

A simple technique for the preparation of powder compounds doped with divalent samarium is described. The reaction is carried out in nickel containers sealed in an inert atmosphere. The samarium impurity is introduced as samarium trifluoride SmF 3 ,

Transfert d'energie entre les ions Ce3+ et Tb3+ dans GdAlO3

Autor: G. Le Flem, Jean Fava, F. Gaume-Mahn, J.C. Bourcet

Publikováno v: Materials Research Bulletin. 11:1-9

Energy transfer from the Ce 3+ to the Tb 3+ ion has been studied in a host GdAlO 3 structure. The maximum fluorescence intensity of Tb 3+ is observed for the composition Gd 0.96 Ce 0.02 Tb 0.02 AlO 3 . The energy transfer from Ce 3+ to Tb 3+ is expla

Publikováno v: Chemical Physics Letters. 51:160-164

Absorption and fluorescence spectra of (RE)VO 4 :Eu 3+ with (RE) = Gd, Y, and Lu are described by phenomenological parameters. Ligand field parameters are determined by taking J -mixing (which arises from the introduction of the ligand field interact
