Lead selenide semiconductor dots (QDs) are a type of II-VI material that exhibit exceptional optical and electronic properties. Their synthesis typically involves solution methods, allowing for precise control over size and shape. The unique tunable nature of these QDs leads to a strong dependence of their band gap on diameter, resulting in narrow
