X-ray Rietveld structure refinement of Ca, Sr and Ba meta-antimonates

Autor: R. A. Young, A. Sakthivel, B. G. DeBoer

Publikováno v: Acta Crystallographica Section C Crystal Structure Communications. 50:476-482

The meta-antimonates, MSb 2 O 6 , M=Ca, Sr and Ba, have been prepared, and their crystal structures refined from powder X-ray diffraction data. The interatomic distances have been determined to reasonable accuracy and the preferred space group was fo

First principles investigation of electronic structure and associated properties of zinc orthosilicate phosphors

Autor: Keith H. Johnson, J. K. Berkowitz, B. G. DeBoer, J. Olsen, E.A. Dale, K. C. Mishra

Publikováno v: Journal of Luminescence. 47:197-206

The electronic structure of willemite phosphor, Zn2SiO4:Mn, has been investigated using the first principles multiple scattered wave Xα cluster method. The various absorptions of this phosphor have been interpreted using the calculated molecular orb

Bands versus bonds in electronic-structure theory of metal oxides: Application to luminescence of copper in zinc oxide

Autor: J. K. Berkowitz, B. G. DeBoer, K. C. Mishra, E. A. Dale, Keith H. Johnson, P. C. Schmidt

Publikováno v: Physical Review B. 42:1423-1430

The fundamental issue of ``bands versus bonds'' in metal oxides is addressed through the direct comparison of results from scattered-wave cluster-molecular-orbital and augmented-spherical-wave band-structure calculations for zinc oxide and copper-imp

Electronic structures and nature of host excitation in Borates

Autor: I. Osterloh, B. G. DeBoer, Volker Eyert, K. C. Mishra, P. C. Schmidt, K. H. Johnson, M. Stephan

We report the electronic structures of three large band gap borates β-BaB2O4, YBO3 and LuBO3, and corresponding binary oxides BaO, Y2O3, Lu2O3 and B2O3. The main objective of this investigation is to explore how the electronic structures of complex

Bands versus bonds in sulfides: Theoretical investigation of the luminescence of copper in zinc sulfide

Autor: K. H. Johnson, P. C. Schmidt, K. C. Mishra, E. A. Dale, B. G. DeBoer, J. Olsen

Publikováno v: Physical review. B, Condensed matter. 43(17)

Explication coherente du processus de luminescence pour divers centres de luminescence du cuivre. Les resultats pour Cu e+ /ZnS confirment le modele de Lambe-Klick pour l'excitation de l'emission infra-rouge, tandis que les calculs pour Cu + , Cl −
