The results of measurements of X‐ray photoelectron spectra (XPS) of a‐SiO2host material after pulsed implantation with [Mn+] and [Co+, Mn+] ions as well as DFT‐calculations are presented. The low‐energy shift is found in XPS Si 2pand O 1score‐levels of single [Mn+] and dual [Co+, Mn+] pulsed ion‐implanted a‐SiO2(E= 30 keV,D= 2×1017cm−2) with respect to those of untreated a‐SiO2. Similar changes are found in XPS Si 2pand O 1sof stishovite compared to those of quartz. This means that the pulsed ion implantation induces the local high pressure effect that leads to the appearance of SiO6‐structural units in a‐SiO2host, forming “stishovite‐like” local atomic structure. This process can be described within an electronic bonding transition from the fourfold “quartz‐like” to sixfold “stishovite‐like” high‐pressure phase in the SiO2host matrix. It is found that such octahedral conversion depends on the fluence and starts with doses higher thanD= 3×1016cm−2.
