Abstract

Two‐dimensional quantum dots have received a lot of attention in recent years due to their fascinating properties and widespread applications in sensors, batteries, white light‐emitting diodes, photodetectors, phototransistors, etc. Atomically thin two‐dimensional quantum dots derived from graphene, layered transition metal dichalcogenide, and phosphorene have sparked researchers’ interest with their unique optical and electronic properties, such as a tunable energy bandgap, efficient electronic transport, and semiconducting characteristics. In this review, we provide in‐depth analysis of the characteristics of two‐dimensional quantum dots materials, their synthesis methods, and opportunities and challenges for novel device applications. This analysis will serve as a tipping point for learning about the recent breakthroughs in two‐dimensional quantum dots and motivate more scientists and engineers to grasp two‐dimensional quantum dots materials by incorporating them into a variety of electrical and optical fields.
