Dye sensitization is a promising route to enhance luminescence from lanthanide-doped upconverting nanoparticles (LnUCNPs) by improving the photon harvesting capability of LnUCNPs through the use of dye molecules, characterized by...

This review provides a historical overview of the role of lanthanide luminescence in scientific advancements that have enabled past, current, and future commercial technologies.

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.
