Abstract

In the present work, solution based simple chemical precipitation method has been used to prepare undoped and Gd
doped ZnS nanoparticles. The prepared nanoparticles were characterized by standard analytical methods the X-ray diffraction results revealed that the undoped and Gd doped ZnS nanoparticles corresponds to hexagonal wurtizite structure.
The FESEM images shows that the formation of agglomerated nanoparticles. The compositional analysis confrmed the
presence of Gd in ZnS matrix with reasonable dissolution range. HRTEM results show that undoped and Gd doped ZnS
nanoparticles exhibit a uniform size distribution with average grain size lying in the range of 2.4–3.9 nm. The magnetic
studies of Gd doped ZnS nanoparticles carried out at room temperature by vibrating sample magnetometer shows that
the materials exhibit magnetic hysteresis. The prepared samples shows paramagnetic behavior at room temperature. The
degradation of methylene blue dye (MB), methyl orange dye (MO) and efuent collected from industry by the undoped
and Gd doped ZnS nanoparticles was studied using 8 W, UV visible lamp light irradiation. The color degradation efciency
for MB is found to be 95%, whereas the color degradation efciency for MO is 97% and for the efuent collected from a
dye industry it was nearly 90%.
