In the past few years, red to near-infrared persistent phosphors activated by transition
metals (Cr 3+ or Mn 2+ ) received much attention. The research was triggered by a recently …

We report deep-red long-lasting persistent luminescence in Cr 3+-doped LaAlO 3 perovskite
phosphor synthesized by solid-state reaction. The LaAlO 3: Cr 3+ sample showed …

We have developed a novel persistent phosphor of LaAlO3 perovskite doped with Er3+, Cr3+,
and Sm3+ (LAO:Er–Cr–Sm), which exhibits long persistent luminescence (PersL) at 1553 …

Cr^3+-activated Y_3Al_2Ga_3O_12 garnet (YAGG:Cr^3+) persistent phosphor has been
recently reported as a potential candidate material for in vivo imaging application. Temperature …

The photoluminescence, persistent luminescence and thermoluminescence properties of
Mg_(0.998-x)Mn_0.002Bi_xGeO_3 (x = 0, 0.001, 0.005, 0.01, 0.02) were investigated. A Mn-Bi …

Various positron emission tomography (PET) probes have been developed to assess in
vivo activities in humans of drug transporters, which aid in the prediction of pharmacokinetic …

Eu2+, Dy3+ co-doped SrAl2O4 crystals show unique luminescent properties as phosphors,
such as long persistence1) 3) and mechanoluminescence, 4), 5) and indeed, these …

In a Ce 3+-Yb 3+ system, two mechanisms are proposed so far namely, the quantum cutting
mechanism and the electron transfer mechanism explaining Yb 3+ infrared luminescence …

Optical and electronic properties of the SrAl 2 O 4 :Eu 2+ ‐Dy 3+ phosphor were investigated
to analyze the mechanisms of its strong and long persistent luminescence. From the …
