In this study. Tb-doped PbTe nanoparticles with variable Tb3+ content were synthesized by a simple hydrothermal technique. The synthesized nanoparticles were characterized by X-ray photoelectron spectroscopy (XPS). scanning electron microscopy (SEM). https://www.jmannino.com/special-deal-A-Magazine-Curated-By-Sacai-quick-pick/
