| Abstract | Cr-doped CdSe nanoparticles have been synthesized by solvothermal technique. The effect of doping on structural, morphological, optical and magnetic properties has been investigated. According to the X-ray diffraction (XRD) study, with the increases in Crdoping concentration in CdSe, the lattice contraction takes place and the structure gets strained whereas the morphological study shows that with increase in Cr-doping particle size decreases. UV-Vis spectroscopy clearly shows blue-shift in the optical band-gap. Pure CdSe nanoparticles are diamagnetic in nature, but, however, with increases in Cr-content (0 - 5 %) in CdSe, they exhibit ferromagnetic behaviour. These synthesised nanoparticles are dilute magnetic semiconductors and are very promising candidates for 'Spintronic' device applications. |
