Achieving photostability in dye-sensitized upconverting nanoparticles and their use in Fenton type photocatalysis
The poor photostability of dye-sensitized upconverting nanoparticles limits their applicability. By covalently encapsulating modified IR820 in a silica shell, the accessibility of oxygen to interact and cause degradation is completely avoided.
