Abstract

The rational design of brighter upconversion nanoparticles (UCNPs) requires a better understanding of the radiationless deactivation pathways in these materials. Here, we demonstrate the potential of excitation power density (P)-dependent studies of upconversion (UC) luminescence intensities, slope factors, and absolute quantum yields (Phi(UC)) of popular beta-NaYF4: 20% Yb3+, 2% Er3+ UCNPs of ...
