Porous NIR Photoluminescent Silicon Nanocrystals-POSS Composites

An innovative strategy is described for synthesizing a new class of porous near infrared photoluminescent organic–inorganic hybrid materials by chemically incorporating hydrogen-terminated silicon nanocrystals into porous polyhedral oligomeric silsesquioxanes (POSS) frameworks while maintaining the integrity of both the POSS cages and silicon nanocrystals intact, an advance that bodes well for applications in the fields of advanced materials, gas adsorption media, and biomedicine. Congratulations to Dongzhi Chen!

Study on In2O3-x(OH)y Nanocrystal Superstructures for Photocatalysis of CO2 Reduction Published in ACSNano

Our group’s study on In2O3-x(OH)y nanocrystal superstructures showed improved activity for photocatalytic reduction of CO2. Transient absorption studies suggested charge transfer between nanocrystals resulting in greater charge separation and longer lifetimes of the photoexcited charge carriers to be the main factor for this observed improvement. Congratulations to Le He!
