- Title
Effect of Terbium Doping on the Structural and Magnetic Properties of ZnS Nanoparticles.

- Abstract
The authors have presented synthesis and structural and magnetic properties of Tb (0, 2, 4, and 6 at.%)doped ZnS semiconducting nanoparticles and employed via chemical co-precipitation process using polyethylene glycol (PEG) as capping agent. X-ray diffraction (XRD) and selected area electron diffraction (SAED) studies confirm the formation of singlephase, cubic structure, nanometric samples (˜10 nm). Highresolution transmission electron microscopy (HRTEM) analyses of the suspensions revealed the size of the particles in the range 5-8 nm. The undoped ZnS sample displayed the expected diamagnetic behavior and the terbiumdoped ZnS samples exhibited room temperature paramagnetic character as a function of Tbdoping concentration.The observed paramagnetism may be due to the random distribution of the terbium ions into the ZnS crystal lattice giving rise to the formation of feeble interaction.
