Mn²⁺ doping inside glass substrate utilizing metal ion beam implantation technique

The Korea multi-purpose accelerator complex (KOMAC) has been providing metal ion beam services such as Cr⁺, Fe⁺, Co⁺, Cu⁺, Mg⁺ and Ni⁺ using a modified Bernas ion source for diverse users. In this study, metal ion implantation facilitated by KOMAC has been utilized to implant Mn⁺ ions into a glass substrate. First, phosphate glass substrate doped with CeBr₃ was fabricated following melt-quenching technique and then Mn⁺ ion beam was irradiated with flounces of 5 × 10¹⁶ ions/cm². The irradiated sample was heat-treated at 400 °C, and characterized by absorption, excitation, and emission spectra. The presence of Mn²⁺ and the existence of energy transfer from Ce³⁺ to Mn²⁺ were explored by characteristic emission and excitation spectra. The emission intensity of Mn²⁺ was significantly higher when excited by Ce³⁺ excitation than Mn²⁺.
