Nanosized ZnGa2O4:Cr3+ Spinets as Highly Luminescent Materials for Bioimaging
(Amer Chemical Soc, 2019-11-01)
In the search for bright probes emitting in the red-to-near-IR region, in the biological transparency window where the absorption and diffusion of light by tissues and the autofluorescence are strongly reduced, Cr3+-doped ...
The Bologna Stone: history's first persistent luminescent material
(E SCHWEIZERBARTSCHE VERLAGSSTUTTGART, 2012)
In 1603, the Italian shoemaker Vincenzo Cascariolo found that a stone (baryte) from the outskirts of Bologna emitted light in the dark without any external excitation source. However, the calcination of the baryte was ...
Persistent luminescence of Eu(2+) and Dy(3+) doped barium aluminate (BaAl(2)O(4):Eu(2+),Dy(3+)) materials
(ELSEVIER SCIENCE BV, 2009)
Polycrystalline Eu(2+) and Dy(3+) doped barium aluminate materials, BaAl(2)O(4):Eu(2+),Dy(3+), were prepared with solid state reactions at temperatures between 700 and 1500 degrees C. The influence of the thermal treatments ...
Persistent luminescence behavior of materials doped with Eu2+ and Tb3+
(OPTICAL SOC AMERWASHINGTON, 2012-04-01)
In this work, the persistent luminescence mechanisms of Tb3+ (in CdSiO3) and Eu2+ (in BaAl2O4) based on solid experimental data are compared. The photoluminescence spectroscopy shows the different nature of the inter- and ...
