“…Pure metals are known to have large L 3 /L 2 ratios due to the abundance of Coster-Kronig decay events, as described below in section 4. Also present in the upper panel is a spectrum from Mn-doped ZnO (formally Zn 0.97 Mn 0.03 O, hereafter referred to as ZnO:Mn), taken from figure 4 of [21]. This spectrum has been included because the SiO 2 :Mn and ZnO:Mn spectra share the presence of the additional peak labeled A in the figure . When the Mn atoms in ZnO:Mn are situated at tetrahedral Zn sites in the lattice, they produce the distinct spectrum shown in figure 4 (see [22] for a second example).…”

Mn(+)-implanted, amorphous SiO(2) samples were synthesized using pulsed-ion implantation without thermal annealing. The crystal and electronic structures have been studied using x-ray diffraction and synchrotron-based soft x-ray absorption and emission spectroscopy at the Si and Mn L(2,3) edges. We find a combination of small MnO clusters and Si crystallites at shallow depths while tetrahedral Mn coordination is found deeper in the host target. Through a combination of techniques, we find that the implantation process simultaneously decreases the long-range order in the near-surface region and increases order deeper in the SiO(2) host. Our results suggest Mn substitution into Si sites at deep levels catalyzes the formation of α-quartz, providing insight into the complex interactions that determine the local structure around the impurities as well as the overall changes to the crystallinity of implanted SiO(2).
