Abstract
Colloidal quantum dots (CQDs) are of enormous interest in the scientific and engineering fields. During the past few decades, significant efforts have been conducted in investigating Cd- and Pb-based CQDs, resulting in excellent photoluminescence (PL) properties and impressive performance in various applications. But the high toxicity of Cd and Pb elements pushed the scientific community to explore low-toxic CQDs excluding poisonous heavy metals. Several semiconductor materials with lower toxicity than Cd and Pb species have been proposed. This article presents a short overview of recent efforts involving low-toxic CQDs, focusing especially on IV–VI and III–V semiconductors which are active in the near- and short-wave-infrared (IR) regimes. Recent achievements pertinent to Sn- and In-based CQDs are highlighted as representative examples. Finally, limitations and future challenges are discussed in the review. Show more
