Abstract

Transparent glass-ceramics are a highly attractive class of materials for photonic applications. Transition metal ions are promising candidates for luminescence centers thanks to the sensitivity of the ligand ions to d-d electron transition. Here, broadband second near-infrared (NIR-II) photoluminescence was achieved via precipitation of ZnGa2O4:Ni2+ nanocrystals within a zinc gallium-silicate glass matrix by a crystallization process. Excited by 260 nm UV photons, ZnGa2O4:Ni2+ GC displays NIR-II emission peaking at 1240 nm and has a full width at half maximum wider than 288 nm, attributed to 3T2g(3F) → 3A2g(3F) electronic transition of octahedrally coordinated Ni2+ ions. Moreover, broad persistent luminescence of Ni2+ ions can be effectively obtained after irradiation in UV light. Based on the electron paramagnetic resonance spectra and a thermoluminescence method, a physical model was constructed to demonstrate the mechanism of persistent luminescence. This developed afterglow luminescent glass-ceramic exhibits potential applications in biological imaging.
