Quantum dots represent a novel and innovative class of nanomaterials, enabling precise adjustments in their absorption and emission properties. Their potential is evident in applications like phosphors and display technologies. The awarding of the Nobel Prize in Chemistry in 2023 has increased the general awareness of quantum dots, making the term familiar to many. From an educational standpoint, the introduction of these advancements into school curricula presents a valuable opportunity, allowing for the development of relevant experiments for educational purposes. The synthesis of zinc oxide quantum dots [1] and carbon quantum dots [2] is already achievable in educational settings.

In order to delve deeper into this subject, we suggest an alternative method of synthesis using a standard microwave. This method involves altering the ratios of reactants and adding additional components, showcasing how these changes can influence the optical properties of the quantum dots. This approach not only highlights the important chemistry concept of structure-property relationships but also serves as an engaging introduction to the fields of spectroscopy and photochemistry. In particular, carbon quantum dots can be employed in photochemical studies of dye degradation [3].
