Hybrid nanocomposites integrating nanostructured zinc oxide (ZnO) and carbon quantum dots (CQDs) with designed heterostructures possess exceptional optical and electronic properties. These properties hold immense potential for advancements across diverse scientific and technological fields. This review article investigates the synthesis, properties, and applications of ZnO‐CQD heterostructure nanocomposites. Recent breakthroughs in fabrication methods are examined, including hydrothermal, microwave‐assisted, and eco‐friendly techniques. Key preparation methods such as sol‐gel, co‐precipitation, and electrochemical deposition are discussed, emphasizing their role in controlling heterostructure formation. This review analyses the impact of heterostructures on optical and electronic properties, such as fluorescence, photoluminescence, and photocatalytic activity. Synergistic interactions between ZnO and CQDs within heterostructures are highlighted, demonstrating how they lead to substantial performance improvements. Applications of ZnO‐CQD heterostructures span solar cells, LEDs, photodetectors, water purification, antimicrobial treatments, gas sensing, catalysis, biomedical imaging, drug delivery, environmental sensing, and energy storage. Insights are provided into refining synthesis methods, enhancing characterisation techniques, and broadening the application landscape. Challenges like stability are addressed, along with strategies for optimised performance and practical implementation.

“…6,7 However, the practical applicability of Cd-based QDs is limited due to environmental concerns. Consequently, recent research has shifted its focus to Cd-free substitutes, including zinc selenide (ZnSe) 12–15 zinc selenide telluride (ZnSeTe), 16–18 indium phosphide (InP), 19,20 and copper indium sulfide (CIS). 21,22 ZnSe-based QDs emerge as promising candidates for Cd-free blue QLEDs due to their narrow full-width at half-maximal values (FWHM) and a broad bandgap of 2.7 eV.…”

“…Quantum-dot light-emitting diodes (QLEDs) made of colloidal semiconductor nanocrystals (NCs) are known for their wide color gamut, high luminance quantum efficiency, and compatibility with low-cost manufacturing and are considered as the candidate of next-generation flat panel displays. − Among the three primary colors for full-color display, semiconductor NCs are able to deliver highly efficient and stable electroluminescence (EL) in red and green colors, while their blue emission is inferior. This is because those blue-emitting NCs have wider bandgaps than the red and green counterparts and are more difficult to inject carriers .…”

The utility of semiconductor nanocrystals (NCs) in light-emitting diodes (LED) has shown great potential in the field of display, whereas the challenge remains in developing efficient and stable cadmium-free blue-emitting LED devices due to the poor photophysical properties of blue-emitting NCs. Herein, we develop a controllable synthesis of Cu−Ga−Zn−S (CGZS) semiconductor NCs that show blue light emission with a relative photoluminescence quantum yield exceeding 90%. Furthermore, we have successfully fabricated a solution-processed quantum-dot LED (QLED) using CGZS NCs, achieving a notable maximum external quantum efficiency (EQE) of 1.00% at a luminance of 100 cd/m 2 . Our work lays a foundational framework for advancing cadmium-free blue-emitting QLEDs and facilitates the development of quantum dot electroluminescent panchromatic displays.
