Researchers have demonstrated a new technique that uses light to tune the optical properties of quantum dots -- making the process faster, more energy-efficient and environmentally sustainable -- without compromising material quality.
Researchers at North Carolina State University have demonstrated a new technique that uses light to tune the optical properties of quantum dots -- making the process faster, more energy-efficient and environmentally sustainable -- without compromising material quality.
"Our new approach uses light to drive the reaction, which requires less energy and allows us to be incredibly precise." The light then triggers reactions that make the green-emitting perovskite quantum dots move closer to the blue end of the spectrum when chlorine is present in the solvent, and closer to the red end of the spectrum when iodine is present in the solvent.
"This is a sustainable way to produce high-quality perovskite quantum dots using light. We're now in the process of scaling up to create perovskite quantum dots for use in optoelectronic devices."Pragyan Jha, Nikolai Mukhin, Arup Ghorai, Hamed Morshedian, Richard B. Canty, Fernando Delgado‐Licona, Emily E. Brown, Austin J. Pyrch, Felix N. Castellano, Milad Abolhasani.
