ZnO nanorods with or without Mn Keywords ZnO/Mn nanorod arrays; Photoluminescence; doping grown uniformly and aligned onto PSPA regardless White light; Hydrothermal synthesis of lattice matching show various photoluminescence (PL) properties. The doped Mn ions in ZnO nanorods were directly observed by X-ray photoelectron spectroscopy 1 Introduction (XPS), and ZnO structures were detected by X-ray diffraction (XRD). As the doping concentration increases, Among semiconductor materials, single-crystal silicon XRD peaks of ZnO nanorods shift to low angle. The shows dominant electronic properties and porous silicon, inﬂuences of doping Mn ions on luminescence properties especially porous silicon pillar array (PSPA) samples, of ZnO nanorods were investigated.
