Abstract

The cover art is attributed to an article entitled “Tuning Photoluminescence and Magnetic Properties of Ag–Ga–S and Zn–Ag–Ga–S Quantum Dots via Mn²⁺ Doping” by Chang Jiang et al. selected as an Editor’s Choice for the 72nd Special Feature, “Research Frontiers of Photoelectrochemical Energy Conversion and Photocatalysis” recommended jointly by the guest editors from The Photoelectro­chemistry Research Group and the editorial board of Electrochemistry. In this article, the authors report the first synthesis of Mn²⁺-doped AgGaS₂ and Ag–Ga–Zn–S quantum dots (QDs) via a one-pot method. These QDs were low in toxicity, and the Mn²⁺-doping improved their photoluminescence quantum yield to as high as 45%. The doping also rendered the QDs paramagnetic and readily detectable by magnetic resonance imaging (MRI). Therefore, those QDs are promising as nanoprobes for both photoluminescence- and MRI-based bioimaging.
