Discovering Scientific Triumphs: UJI’s Big Contributions

The scientific challenges of the OHPERA research have resulted in two groundbreaking papers by the UJI partners that promise to reshape the landscape of perovskite nanocrystals (PNCs) applications.

Efficient Ligand Passivation Enables Ultrastable CsPbX3 Perovskite Nanocrystals in Fully Alcohol Environments

In their paper published in March 2023, UJI researchers achieved exceptional stability of CsPbX3 nanocrystals in fully alcohol environments. The strategy involved using didodecyldimethylammonium bromide (DDAB) for surface defect passivation. This innovation extended the stability of CsPbBr3 PNCs up to 7 months in methanol/butanol, showcasing near-unity photoluminescence quantum yield. The approach was also applied successfully to stabilise iodine-based CsPbBr3-xIx and CsPbI3 PNCs, enhancing their optical features and stability in high polar alcohols up to 6 hours. DDAB played a key role in suppressing defects and reinforcing surface passivation, paving the way for long-term stable CsPbX3 PNCs.


Impact Of Core–Shell Perovskite Nanocrystals for LED Applications: Successes, Challenges, and Prospects

This July 2023 publication dives into the successes, challenges, and prospects of PNCs in light-emitting diode (LED) applications. The study underscores the critical role of stabilising PNC phases and passivating surfaces to enhance both stability and optical properties. Exploring various core/shell PNC combinations and their synthesis steps, the paper provides insights for future LED applications and advanced characterisation. Challenges and opportunities in the realm of core/shell PNCs are thoroughly examined, offering a comprehensive view of the strides made and the path forward.
