Abstract

We have synthesized rare-earth doped sub-10 nm diameter upconverting yttrium oxide based nanophosphors by flame spray pyrolysis. We have investigated the emitted visible fluorescence of the sub-10nm nanophosphors under both infrared excitation and electron excitation, and observed comparable narrow band emission spectra. The viability of the nanoparticles for biological imaging was confirmed by imaging the digestive system of the nematode worm C. elegans in the upconversion mode. We have surface functionalized the nanophosphors making them suitable for bio labeling.
