The Rare-Earth Elements

2023
In this section, the elemental forms of rare-earth elements are iron gray to silvery lustrous metals that are typically soft, malleable, ductile, and usually reactive, especially at elevated temperatures or when finely divided. rare-earth elements are examined in terms of physical and chemical properties. This makes them essential components of diverse

Rare-Earth and Transuranic Elements

Physical Review, 1941
Verf. zeigt das starke Absinken der Energie und das Schrumpfen der räumlichen Ausdehnung der \(4f\)- bzw. \(5f\)-Eigenfunktion beim Überschreiten der ungefähren Kernladungszahl \(Z = 57\) bzw. \(Z = 92\). Dieses Vorkommnis bedeutet, daß von diesen Ordnungszahlen ab die \(4f\)- bzw. \(5f\)-Bahnen zu inneren Elektronenbahnen werden.

Rare‐Earth‐Element‐Ytterbium‐Substituted Lead‐Free Inorganic Perovskite Nanocrystals for Optoelectronic Applications

Advances in Materials, 2019
Lead‐(Pb‐) halide perovskite nanocrystals (NCs) are interesting nanomaterials due to their excellent optical properties, such as narrow‐band emission, high photoluminescence (PL) efficiency, and wide color gamut.

The Rare-earth Elements

1971
Mossbauer spectroscopy of the rare-earth elements as a group has gained considerable attention from physicists. Successive addition of 4f-electrons along the series has little influence on many of the chemical properties, which are mainly those of a tripositive cation.
