In this study uncoated and silica-coated yttrium oxide nanophosphors doped with Tb ion were made by flame aerosol synthesis. The effect of the silica coating on the biocompatibility of these nanophosphors was explored. Finally, the employment of such nanoparticles for the detection of cancerous cells is explored.
