Detection of d-d* transitions of vanadium ions in Zn0.97V0.03Se monocrystal by optical absorption spectroscopy

By using optical absorption spectroscopy (both polarized and non-polarized radiation), we have detected for the first time the transitions corresponding to (2)A(2)(F), E-2(D), T-2(1)(H), T-2(2)(F) and the doublet E-2, T-2(2)(D) of excited states of V2+ (d(3)) ions. In addition to this, we have observed structural details which were originated in the charge transfer process. The transition from the ground state Of V2 ions to the bottom of the conduction band was also revealed in the absorption spectrum. Detection of d*-d transitions can be useful to recalculate the parameters of the crystal field splitting (e.g. Racahs parameters) in this system. (C) 2004 Elsevier B.V. All rights reserved.
