Zhuoying and Iek-Heng are giving talks on their work on Na3PS4 and Li7P3S11 solid electrolytes at the 229th ECS Meeting in San Diego. Both talks are in the morning (9am and 11:30am) Wed Jun 1 in the Symposium A04 – Battery Modeling and Computation at the Hilton San Diego Bayfront – Indigo 202A. Also, Prof Ong is one of the organizers of Symposium A04.
Congratulations to Zhenbin on his first paper “Electronic Structure Descriptor for Discovery of Narrow-Band Red-Emitting Phosphors” in Chemistry of Materials! Narrow-band red-emitting phosphors are a critical component in phosphor-converted light-emitting diodes for highly efficient illumination-grade lighting. In this work, we report the discovery of a quantitative descriptor for narrow-band Eu2+-activated emission identified through a comparison of the electronic structure of known narrow-band and broad-band phosphors. By incorporating this descriptor in a high throughput first principles screening of 2,259 nitride compounds, we identify five promising new nitride hosts for Eu2+-activated red-emitting phosphors that are predicted to exhibit good chemical stability, thermal quenching resistance and quantum efficiency, as well as narrow-band emission.
