Transition metal (TM) ion activated phosphors are increasingly being used as probes for
luminescence thermometry. Their luminescence is characterized by strong absorption and …

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 …

Temperature is important because it has an effect on even the tiniest elements of daily life
and is involved in a broad spectrum of human activities. That is why it is the most commonly …

Gaining greater understanding of the structural and functional properties of living systems is
a key challenge in biology and medicine. On a more practical side, the diagnosis and …

The photoluminescence properties of rare-earth (lanthanide) compounds have been
fascinating researchers for decades. 1-14 An attractive feature of luminescent lanthanide …

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 …

Publisher Summary The intensities of intraconfigurational f–f transitions are reviewed in the
chapter. The chapter presents the transition mechanisms for lanthanide ions—namely, the …

Commercial white LED devices usually suffer from a high color temperature and poor color
rendering. Developing a new, efficient, and stable red phosphor is the key to solving this …

Rare-earth β-diketonates are complexes of β-diketones (1, 3-diketones) with rare-earth ions.
These complexes are the most popular and the most intensively investigated rare-earth …

Trivalent lanthanide ions display fascinating optical properties. The discovery of the
corresponding elements and their first industrial uses were intimately linked to their optical …
