Distinct Thermal Quenching of Upconversion and Downshifting Luminescence Caused by Dynamic Defects in Ion-conductive Na3Sc2(PO4)3∶Yb3+, Er3+ Phosphor
“Researchers have delved into the luminescence of Yb3+/Er3+ in the Eu2+-doped Na3Sc2(PO4)3 ionic conductor, revealing the mechanism behind its superior thermal quenching resistance. The study uncovers that thermally accelerated dynamic defects/ions enhance radiative transitions and suppress non-radiative ones, leading to significant negative thermal quenching of upconversion luminescence and thermal stabilization of downshifting luminescence. This work paves the way for a deeper understanding of luminescence mechanisms through dynamic defects/ions.”
