Structural,Optical And Magnetic Properties of Dy with Mn CoDoped Zns Nanoparticles By Using Co-Precipitation Method
Journal Title: International Journal of Engineering and Science Invention - Year 2017, Vol 6, Issue 9
Abstract
In this present work, Mn, Dy co-doped ZnS nanoparticles were prepared at room temperature using chemical co-precipitation method. The water soluble PVP were used as capping agents for the synthesis of Dy, Mn co-doped ZnS nanoparticles. The nanostructure of the synthesized Dy, Mn co-doped ZnS nanoparticles were characterized by powder X-ray diffraction (XRD), Scanning election microscope (SEM), Energy dispersive analysis of X-rays (EDAX), diffuse Reflectance spectroscopy (DRS)and Vibrating Sample Magnetometer (VSM). The size of as prepared Dy, Mn co-doped ZnS nanoparticles is found to be around ~2 nm range. Broadened XRD peaks confirmed the formation of nanoparticles with face centered cubic (FCC) structure. SEM along with EDS gave the size, morphology and compositional analysis of as prepared material. DRS studies show that the effective band gap energy increases with increasing dopent concentration. The M–H loop of Dy, Mn co-doped ZnS Nanoparticleshas been traced using the VSM and magnetic parameters such as saturation magnetization (MS), coercivity (HC) and retentivity (Mr) are obtained from VSM data.
