Scheelite like NaTb(WO) nanoparticles: Green fluorescence and in vitro cell imaging applications.

This study highlights the investigation of the green fluorescence in NaTb(WO) materials (NaTbW Bulk and NaTbW Nano) synthesized via template free hydrothermal method as a function of particle size and morphology. Herein, we demonstrated the biocompatibility and intracellular green fluorescence of NaTbW Nano samples using HeLa cells for cell imaging applications. Powder X-ray diffraction studies showed that the as synthesized NaTbW Bulk and NaTbW Nano crystallize in the Scheelite like tetragonal crystal system with the I4/a space group.
