Room temperature ferromagnetism in Nd doped ZnS diluted magnetic semiconductor nanoparticles

Nanoparticles of ZnS:Nd (0, 2 and 4at%) were synthesized by a chemical co-precipitation method at 300K using PEG as capping agent. The effect of Nd doping on the structural, optical and magnetic properties of ZnS nanoparticles was investigated. EDAX spectra confirmed the presence of Zn, Nd and S in...

Description
Summary:Nanoparticles of ZnS:Nd (0, 2 and 4at%) were synthesized by a chemical co-precipitation method at 300K using PEG as capping agent. The effect of Nd doping on the structural, optical and magnetic properties of ZnS nanoparticles was investigated. EDAX spectra confirmed the presence of Zn, Nd and S in the samples. X-ray diffraction studies showed that all the samples exhibited the expected zinc blende structure. Raman studies revealed the cubic structure and absence of impurities in the undoped and Nd doped ZnS nanoparticles. TEM studies indicated that the particles were a few nm (
