The structural, optical and dielectric properties of the rare earth Terbium (Tb3+) doped CdSe one dimensional semiconductor nanorods has been explored. The pure and 0.5% Terbium (Tb3+) doped CdSe nanorods were synthesized by using hydrothermal method at a moderate temperature of 180°C. The prepared samples were characterized by X – ray diffraction, Scanning Electron Microscopy (SEM), Energy Dispersive X–ray diffraction (EDX) analyses. The X–ray diffraction (XRD) study shows the wurtzite structure for pure and Tb3+ doped CdSe nanorods. The band gap of the pure and doped CdSe nanorods was found. PL The strong PL intensity confirms a blue shift. The dielectric and electrical conductivity studies of pure and Tb3+ doped CdSe were carried out.

Keywords- Nanoparticles, nanorods, CdSe, Tb3+doped CdSe, SEM, dielectric study
