Title: Plasmonics for Brighter Displays: Unlocking Perovskite Quantum Dots for Next-Gen Optoelectronics
Perovskite quantum dots are emerging as key materials for the future of vibrant and energy-efficient displays. In this webinar, I present an approach that couples gold nanoparticles with perovskite QDs to dramatically boost their brightness and efficiency. By accelerating radiative recombination through plasmonic interaction, the system achieves near-unity photoluminescence in solution and delivers highly efficient green emission when paired with blue LEDs. This enables power efficiencies exceeding 140 lm W鈦宦� while maintaining excellent color purity aligned with advanced display standards. The technology is also fully compatible with micro-scale photopatterning, supporting seamless integration into next-generation micro-LED panels. These advancements open practical pathways toward thinner, brighter, and more sustainable display devices.

Title: Nanoscale Chiral Materials for Multidisciplinary Studies: From Energy Conversion路Storage to Theranostics
The chirality of nanostructured systems has gained attention in catalysis, biotechnology, optoelectronics, spintronics, etc., owing to their enantio-/spin-selective interactions and chiroptical features. However, large-scale fabrication of chiral inorganic nanostructures remains challenging. We report precision engineering and supramolecular self-assembly based nanofabrication of hybrid chiral nanostructures and exploit their unprecedented applications. We show chiro-optical, magneto-optical, catalytic energy conversion, circularized light emission and theranostic properties from libraries of chiral inorganic nanostructures and block copolymer supramolecules. Our design concept pinpoints steps to construct an extended library of viable chiral nanostructures, aiding the development of artificial chiral materials.
