In this review, modern insights into the synthesis and fundamental optical properties as well
as applications of divalent lanthanides as spectral energy converters are discussed, which …

Seminal author George Blasse concluded his lecture Classical Phosphors: A Pandora's Box
delivered at the International Conference on Luminescence 1996 held in Prague with the …

Photoluminescence (PL) features arising from intraconfigurational 4f–4f transitions and also
O 2−→ Ln 3+ charge transfer (CT) where Ln 3+= Yb 3+, Sm 3+ or Eu 3+ are observed for Ln …

Lanthanides are multivalent chemical systems whose luminescence activates numerous
optical devices. Their multivalent nature sets a complex scenario that challenges …

Yb-substituted CaF2 exhibits an anomalous red-shifted luminescence after UV excitation,
attributed to the relaxation of impurity trapped excitons (ITE). CaF2: Yb is the archetype …

Materials that luminesce after excitation with ionizing radiation are extensively applied in
physics, medicine, security, and industry. Lanthanide dopants are known to trigger crystal …

The relaxation pathways of states in the energy region of the fundamental absorption of
NaMgF 3: Yb 2+ and MgF 2: Yb 2+ are investigated using time-resolved vacuum ultraviolet …

NaMgF3 is a host material that has demonstrated luminescent properties suitable for
radiation dose measurements when doped with lanthanide (Ln) ions. NaMgF3 has a …

In Chap. 7, the diabatic approximation was shown to offer an elegant recipe to obtain
qualitative and in many cases quantitative information on electron transfer processes …

The luminescence of crystalline compounds can be used to monitor many physical
phenomena, including doses of ionising radiation. Optically stimulated luminescence (OSL) …
