The trivalent europium ion (Eu 3+) is well known for its strong luminescence in the red
spectral region, but this ion is also interesting from a theoretical point of view. Due to the …

The red or orange emission spectra of tripositive europium have led to thousands of
publications and to phosphor applications. The orange emission mainly arises from the 5 D …

Regularities among electronic configurations for common oxidation states in lanthanide
complexes and the low involvement of f orbitals in bonding result in the appearance of …

Ever since the Rare Earths became known as a group composed of sixteen elements (ie
scandium, yttrium, and the elements lanthanum through lutetium), whose discovery and …

We report photo and thermoluminescence properties of Zn 2 SiO 4: Re 3+(Eu, Dy, Sm)
phosphors prepared by low temperature solution combustion technique. The hexagonal …

In this work the aim is three-fold: 1) to call attention for shielding effects in the energy transfer
rates between lanthanide ions. 2) to use a new model for treating the Judd-Ofelt Ω K …

The best available energy level data for the cubic Cs2NaLnCl6 and Cs2NaYCl6: Ln3+
(doped) systems are collected together and summarized. These data are analyzed in terms …

In efforts to study the periodic chemical properties of the rare earth elements and their
structural chemistry, a hybrid double perovskite phase A2B′ BX6 with the formula ((CH3) …

Publisher Summary This chapter discusses the factors that lead to the formation of rare earth
complexes and illustrates examples of the various types of complexes that are prepared …
