Autor: A. S. Voloshinovskii, V. O. Karnaushenko, A. Gektin, V.V. Vistovskyy, Ya. M. Chornodolskyy, S.V. Syrotyuk
Publikováno v: Journal of Luminescence. 237:118147
The energy band structure of CeX3 (X = Cl, Br, I) crystals have been calculated by the methods of density functional theory using projector augmented waves and hybrid functional of the exchange-correlation interaction PBE0. The valence bands of the i

Publikováno v: Journal of Luminescence. 225:117346
The work reports the results of spectroscopic and luminescence-kinetic studies of CsPbBr3 single crystal over 14–300 K temperature range. It is shown that at low temperatures the luminescence spectrum contains three narrow bands at 534, 537, and 54
