Luminescence of holmium(III) ions activated by titanium(III) ions in potassium-aluminum-silicon phosphate glass

Abstract

A potassium-aluminum-silicon phosphate glass based phosphor activated by holmium(III) and titanium(III) was synthesized. It is demonstrated that holmium luminescence in the glass under study is sensitized by titanium ions by the dipole-dipole mechanism. No visible reverse energy transfer in the Ho³⁺→Ti³⁺ pair was observed.
