What Does It Cover?
Quantum Dots (QDs) undoubtedly attracted lots of interest with their superior luminescent properties. What is distinct about their luminescent properties is that the wavelengths of emitted light can be precisely tuned by changing of nanoparticle size or composition. Quantum dots possess narrow full width at half maximum (FWHM), high photoluminescence quantum yield (PLQY), emission wavelength tunability through the entire visible and near IR range. In this webinar, we talk about synthesis and application of emerging quantum dots materials: Perovskite and PbS QDs. Perovskite QDs emit light within the visible range, have high PLQY (up to 100 %), narrow FWHM (below 20-25 nm), and are considered as the best alternatives for CdSe and InP QDs for display application. PbS QDs emit light in near IR region with narrow FWHM of absorption and emission, making them ideal in NIR photodetectors and solar cells.

Osman M. Bakr, PhD
King Abdullah University of Science and Technology (KAUST)
Associate Professor of Materials Science and Engineering
Osman M. Bakr is an Associate Professor of Materials Science and Engineering at KAUST, Saudi Arabia. He holds a B.Sc. in Materials Science and Engineering from MIT (2003) as well as a M.S. and a Ph.D. in Applied Physics from Harvard (2009). The research group he founded at KAUST studies the design and self-assembly of hybrid organic-inorganic materials and nanomaterials for breakthrough applications optoelectronics. Bakr’s research group has published >120 articles in high impact scientific publications, including Science.
Bakr was selected as a Young Scientist by the World Economic Forum (2016) and as an Emerging Investigator by the Journal of Materials Chemistry A (2016). He was awarded the SABIC Endowed Presidential Career Development Chair (2013), the Zasshi-kai Lectureship Award by the University of Tokyo (2016), and the Innovator Under 35 Award in the Arab World by the MIT Technology Review- Arab Edition (2016). In 2018, he was ranked by the Times Higher Education among the top 10 university researchers world-wide in the area of “perovskite solar cells”. He currently serves on the editorial advisory boards of the American Chemical Society (ACS) journals Chemistry of Materials and ACS Energy Letters.
