Microwave‐Facilitated Sensitization Route Boosting Efficiency, Thermostability, and Multifunction of Nanophosphors

open access: yesAggregate, EarlyView.
A microwave‐facilitated sensitization engineering is proposed to construct new NSYP:Ce,Tb NPs with less oxygen vacancy, suppressing energy loss of Ce sensitizers and transferring more energy to Tb activators. As a result, the Ce sensitization for Tb achieves ultrahigh ET efficiency (92.6%), contributing to high IQE of 82.2%, along with outstanding ...
