The wavelength-ratiometric techniques gain increasing popularity in fluorescence probing
and sensing for providing inner reference to output signal and removing instrumental …

In terms of the combined advantages of upconversion luminescence (UCL) properties and
dual-signal ratiometric outputs toward specific targets, the ratiometric UCL nanoprobes …

Förster resonance energy transfer (FRET)‐based devices have been extensively
researched as potential biosensors due to their highly localized responsivity. In particular …

A series of novel Sn 2+ doped boroaluminate glasses were prepared by the traditional melt
quenching method in this work. Their glass network structure, luminescent properties, and …

A novel force sensor exploiting the interaction between plasmonic nanostructures and
upconversion nanoparticles (UCNPs) is reported. The nanosensor is composed of a gold …

This dissertation reports on the fabrication and characterization of nanostructured materials
for optical sensing applications. In the first project, we studied how upconverting …

Upconverting nanoparticles are notorious for their ability to absorb multiple photons and
emit one with a shorter wavelength. Given that the human body is more transparent to …
