Vacuum Referred Binding Energy of the Single 3d, 4d, or 5d Electron in Transition Metal and Lanthanide Impurities in Compounds

The vacuum referred binding energy (VRBE) of the single electron in the lowest energy 3d level of Sc2 +, V4 +, Cr5 +, the lowest 4d level of Y2 +, Zr3 +, Nb4 +, Mo5 + and the lowest 5d level of Ta4 +, and W5 + in various compounds are determined by means of the chemical shift model. They will be compared with the VRBE in the already established...

Vacuum Referred Binding Energies of the Lanthanides in Transition Metal Oxide Compounds

The electronic level schemes for divalent and trivalent lanthanide ions in rare earth (La, Gd, Y, Lu, Sc) vanadate, niobate, tantalate, and in alkaline earth (Ba, Sr, Ca, Mg) titanate, molybdate, and tungstate compounds are presented. Use is made of data from luminescence excitation and absorption spectra of lanthanide (mostly Eu3 +, Pr3 +, and...

Systematics in the optical and electronic properties of the binary lanthanide halide, chalcogenide and pnictide compounds: An overview

The basic optical, electrical and chemical properties of the binary divalent, trivalent and tetravalent lanthanide (Ln = La, . . . , Lu) halides (F, Cl, Br and I), chalcogenides (O, S, Se and Te) and pnictides (N, P, As and Sb) were studied using an empirical model that utilizes the systematic behaviour in the energy difference between the...

The thermally induced metal–semiconducting phase transition of samarium monosulfide (SmS) thin films

High quality phase pure samarium monosulfide (SmS) thin films were prepared by electron beam evaporation using a samarium metal source in a H2S atmosphere. The optical properties (reflection, transmission, absorption) of the films in the semiconducting and metallic phase were analysed from the UV to the mid-IR and explained in terms of the...
