In this work, the synthesis of neodymium doped ZnO (Zn_1−xNd_xO, x=0.0, 0.03, 0.06 and 0.09) nanoparticles by a co-precipitation method with improved magnetic property is reported. X-ray diffraction pattern indicates that most of Nd³⁺ ions are incorporated in Zn²⁺ ions of ZnO lattice and hence there is no secondary peak of NdO₃ in synthesized ZnO nanoparticles (NPs). The FTIR analysis of synthesized NPs exhibits similar patterns in Zn/Nd–O bands observed at 480 cm⁻¹. HRSEM images revealed the formation of spindle like morphology for pure and Nd doped ZnO with average particle size of 200–300 nm. The incorporation of Nd ions is confirmed by energy dispersive X-ray analysis (EDX). The photoluminescence (PL) measurements revealed broad emission which was composed of different bands due to zinc and oxygen vacancies. X-ray photoelectron spectroscopy (XPS) confirmed the Nd incorporation in …
