Novel double perovskite SrLaLiTeO6 (abbreviated as SLLT): Mn4+, Dy3+ phosphors synthesized by solid-state reaction strategy exhibits distinct dual-emitting of Mn4+ and Dy3+. High-sensitivity and wide-temperature-range dual-mode optical thermometry was exploited...
Nowadays, there is an enthusiastic effort to develop the luminescent thermometers used for remote and high-sensitivity temperature readout over a wide sensing range. Herein, the Pr3+ and Gd3+ co-doped ZrO2...
Eu[Formula: see text]/Tb[Formula: see text] co-doped nanocomposite containing CeO2 nanocrystals was successfully prepared by an in situ sol–gel polymerization approach. High-resolution transmission electron microscopy demonstrated the homogeneous precipitation of CeO2 nanocrystals among the polymethylmethacrylate (PMMA) matrix. The thermal stability and UV-shielding capability of the obtained nanocomposite were improved with increase of CeO2 content. The tuning of the emissive color from green and yellow to red can be easily achieved by varying the dopant species and concentration. These results suggested that the obtained nanocomposite could be potentially applicable in transparent solid-state luminescent devices.
