A new model is proposed for the electronic configuration of the trivalent lanthanide metals in the condensed state. It is suggested that there are two kinds of 4 electrons鈥攖he "atomic" 4 electrons and the 4 "band" electrons. The former are the 4 electrons which are commonly associated ...
Acidity Scale for Metal Oxides and Sanderson's Electronegativities of Lanthanide Elements Acid trip: A general scale that compares the acidities of metal oxides and sulfides quantitatively is presented, along with Sanderson's electronegativity v... NakCheon,Jeong,JiSun,... - 《Angewandte Chemie》...
It is worth mentioning that the standard DFT, which utilizes the local density approximation (LDA) or the generalized-gradient approximation (GGA), often fails to predict the electronic properties of materials containing transition metals or Ln-elements. This discrepancy occurs due to Self-Interaction...
occupying an excited energy state. The two lanthanide ions populate the excited state with higher energy in the first lanthanide ion to further initiate CR. This process exponentially increases the electronic population of the excited state with higher energy in the first lanthanide ion through ESA, ...
The reference to 4f ions, of course, is a reference to the rare-earth elements, otherwise known as the lanthanide series of elements, generally considered to have atomic numbers from 58 through 71 and varying degrees of filling of the 4f shell of the electronic configuration of ions may have...
Although an opposite trend may operate for the actinides29, it may be that the more diffuse 5f orbitals could tolerate occupancy more; however, thus far the radioactivity of those elements has precluded any detailed body of experimental work from being compiled and hence further work will be ...
The use of lanthanide-containing building blocks adds several features that are unique, fundamentally interesting, and practically significant to the construction of MOFs, due largely to the traits originated from the unique /-electronic configuration of these elements; these include primarily ionic metal...
these elements across the series; La3+is the least Lewis acidic cation and Lu3+is the most Lewis acidic of the lanthanide series. The RE elements have many uses in everyday life. Their electronic characteristics are applied in electronic displays, magnets, and wind turbines, among other ...
The luminescence of lanthanide materials, in this context, is helpful and superior over the traditional organic dyes, green fluorescent protein (GFP) or even QDs as lanthanide elements possess abundant metastable energy levels and rather long-lived excited states in their 4f orbitals. Lanthanide ions...
