F 97 Fundamental absorption edge of NiO nanocrystals [Electronic resource] / V. I. Sokolov, A. V. Druzhinin, D. G. Kim, N. B. Gruzdev, A. Ye. Yermakov, M. A. Uimin, I. V. Byzov, N. N. Shchegoleva, V. B. Vykhodets, T. E. Kurennykh // Physica B: Condensed Matter . - 2013. - Vol. 430. - С. 1-5. - Bibliogr. : p. 5 (29 ref.) Рубрики: ХИМИЧЕСКИЕ НАУКИ Кл.слова (ненормированные): TRANSITION METAL OXIDE -- OPTICAL PROPERTIES -- CHARGE TRANSFER TRANSITIONS Аннотация: NiO nanocrystals with the average size of 5, 10 and 25 nm were synthesized by gas-condensation method. The well-defined increase of the optical density D near the fundamental absorption edge of NiO nanocrystals in the range of 3.5–4.0 eV observed after the annealing in air is caused by the oxygen content growth. It is the direct experimental evidence of the fact that p—d charge transfer transitions form the fundamental absorption edge \\\\expert2\\NBO\\Physica B\\2013, v.430, p. 1-5.pdf |
