In this work, we report on the short and long range order of single room temperature‐implanted and high temperature‐implanted Co:ZnO nanowires using hard X‐ray nanoprobe‐based techniques. X‐ray fluorescence maps reveal a homogeneous distribution of the Co ions implanted along the nanowires. X‐ray absorption near edge structure data indicate a substitutional incorporation of Co 2+ into the wurtzite ZnO host lattice. The room temperature‐implanted nanowires present a higher structural disorder around Co atoms compared to the high temperature‐implanted ones. X‐ray diffraction results show a crystal lattice expansion induced by the ion implantation process in the room temperature‐implanted nanowires. Micro‐photoluminescence data corroborate these findings and exhibit an excellent optical activation of the incorporated Co ions in the high temperature‐implanted nanowires.
