Kim Jae Woo and Kim Hee Eun, Master's students in the Nano Chemistry Major at our university's Graduate School (supervised by Professor Kim Young Hoon), were awarded the Best Poster Presentation Award and the Excellent Poster Presentation Award respectively in the poster presentation category at the ‘Korean Society of Polymer Science Autumn Conference’ held from 29 September to 1 October.

This presentation conference was held under the theme ‘Expanding the Frontiers of Future-Oriented Materials Technology’. Student Kim Jae Woo presented on ‘Synthesis of High-Colour-Purity/High-Stability CsPbBr₃/Cs₄PbBr₆ Core/Shell Nanostructure Perovskite Nanocrystals via Oleylamine-Induced Phase Transition’, whilst Kim Hee Eun presented on ‘Facet–Growth Correlation Bypass Enables Dimensional Tuning in Blue-Emissive Perovskite Quantum Dots’.

This research holds significance in synthesising high-colour-purity, high-stability perovskite nanocrystals via a simple process, unlike other core-shell strategies applied to existing perovskite nanocrystals (Kim Jae Woo). It received high praise for proposing a novel synthesis strategy that controls the crystallisation directionality of perovskite blue light-emitting materials, thereby demonstrating the potential for developing high-colour-purity, high-stability blue nanocrystals (Kim Hee Eun).

This achievement serves as a testament to the excellence and creativity of the next-generation luminescent material research pursued by the CENL Laboratory in the Department of Chemistry at Kookmin University. It is anticipated to contribute significantly to the future development of high-efficiency luminescent materials and devices.
