Tunable Near Infrared to Ultraviolet Upconversion Luminescence Enhancement in (alpha-NaYF :Yb,Tm)/CaF Core/Shell Nanoparticles for In situ Real-time Recorded Biocompatible Photoactivation

Nanoscience and Nanotechnology
A family of upconverting nanoparticles (UCNPs) with a tunable UV enhancement is developed via a facile approach. The design leads to a maximum 9-fold enhancement in comparison with known optimal beta-phase core/shell UCNPs in water. A highly effective and rapid in situ real-time live-cell photoactivation is recorded for the first time with such nanoparticles.
