Ab initio model potential (AIMP) embedded cluster calculations of the absorption spectrum of Cs2GeF6:Mn4+ show unusually large dicrepancies with very accurate experimental data in electronic transition energies that involve an effective single excita

The donor and acceptor charge-transfer transitions in YAlO{sub 3}:Ti{sup 3+}/Ti{sup 4+} were investigated through absorption, emission, excitation, one-photon and two-photon photoconductivities, excited-state absorption, and thermoluminescence. The r

The point of this article is to investigate under what conditions the sum of a donor transition of an impurity ion, Mn+ → M(n+1)+ + e(CB), and an acceptor transition M(n+1)+ + e(VB) → Mn+ is equal to the band gap of the host. Our recent work on T

The title compounds contain diamagnetic Cu(III) in nearly square planar CuO4 units linked to each other by alkali ions. The optical and vibrational spectra were measured. A d—d transition at 12,000 cm−1 and a charge transfer transition at 22,000

Photoconductivity of Ti 3+ in Al 2 O 3 , Y 3 Al 5 O 12 and MgAl 2 O 4 were studied by one-step and two-step ionization at room and liquid-nitrogen temperatures. By virtue of its selectivity, two-step photoconductivity can give more accurate ionizatio

One and two photon spectra of Mn 4+ in Cs 2 TiF 6 have been reported. A detailed analysis of these spectra testifies the presence of a strong electron-vibration coupling in this system. A novel consequence of this interaction, a reduction of the spin

Consequences of electron-vibration coupling have been investigated using one- and two-photon spectra of Mn 4+ in cubic Cs 2 GeF 6 and Cs 2 SiF 6 . The observations clearly demonstrate a linear Jahn-Teller effect, a Ham effect in electronic and vibron
