Abstract

Dysprosium-doped ZnO nanoparticles [Zn1−xDyxO] were studied to enhance and control their multifunctional properties for various optoelectronic or magnetoelectrical properties. After synthesizing well-defined Dy-doped ZnO nanoparticles by Sol-Gel route, the evaluation of optical, magnetic, and electrical characteristics of synthesized ZnO nanoparticles was done. Formation of hexagonal wurtzite structure of Dy-doped nanoparticles was recognized by XRD studies and morphology, by transmission electron microscopy (TEM). The effect of the increase in dopant concentration on the bandgap was confirmed by UV-vis spectra. PL study was performed to show the presence of various types of defects in synthesized nanoparticles. In magnetic studies, room-temperature ferromagnetism (RTFM) behavior was observed. Four probe method showed the dependence of resistivity on dopant concentration.
