Scientists 3D print luminescent quantum dot-polymer architectures with potential for advanced optoelectronics

Quantum dots, nanoscale semiconductors with unique light-emitting properties, have garnered excitement for years due to their potential to revolutionize technologies from solar cells to biomedical imaging. In particular, quantum dots made of organic-inorganic hybrid perovskite materials exhibit exceptional properties like color tunability, narrow emission bands, and high quantum yields. However, harnessing perovskite quantum dots' capabilities has proven challenging, as they are sensitive to heat and oxygen.
