Lanthanide-doped phosphors with persistent luminescence have attracted much interest
owing to their unique “self-luminescing” feature and broad potential applications. Among all …

Tb-doped GdTaO4 crystals were synthesized to investigate their photoluminescence and
scintillation properties. Tb: GdTaO4 exhibits photo-and radioluminescence characterized by …

In this work, the dense bulk polymorphous YTaO4 ceramics with M or M'phase are
synthesized by spark plasma sintering method accompanying with different tempering …

The electronic level schemes for divalent and trivalent lanthanide ions in rare earth (La, Gd,
Y, Lu, Sc) vanadate, niobate, tantalate, and in alkaline earth (Ba, Sr, Ca, Mg) titanate …

This book gives an overview on the fundamentals and recent developments in the field of
luminescent materials. Starting from the definitions and properties of phosphors, novel …

So far, overcoming thermal quenching remains a huge challenge in the application of
phosphor materials. The intervalence charge transfer (IVCT) state has an inestimable role in …

The optical properties of undoped polycrystalline ceramics NdTaO 4 (NTO), ErTaO 4 (ETO)
and YbTaO 4 (YTO) were investigated for the first time to our knowledge. The ceramics were …

A dual tunable visible (reddish, orangish, blueish and white emission) and near infrared
energy conversion in Pr 3+-doped yttrium tantalate prepared by sol-gel method were …

Pr-doped GdTaO 4 crystals with various Pr-concentrations were prepared using a floating
zone furnace, and the photo-and radio-luminescence properties were evaluated. Pr: GdTaO …

Tantalate is considered as a valuable and efficient luminescence host because of its intense
absorption in the ultraviolet area and excellent chemical properties. In this work, a series of …
