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 …

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 …

Narrow dips were found in the excitation spectra of crystals of alkaline earth fluorides doped
with Er F 3 or/and Yb F 3. The positions of the dips are in good agreement with the positions …

While considering metal oxides co-doped by non-rare earth ions potential for non-contact
luminescence thermometry applications, a series of novel Ba 2 LaTaO 6: Bi 3+, Mn 4+ …

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 …

Single crystals of Ca 1–y Sr y R х F 2+ х (R= Ho, Pr) solid solutions with high optical quality
have been grown by the Bridgman technique in vacuum using a fluorination atmosphere …

Ytterbium-doped wide-bandgap fluoride crystals CaF 2, SrF 2 and NaMgF 3 have been
measured using x-ray absorption near edge structure (XANES) on the L3 edge to determine …
