Light Induced Self-Inscription (LISI) in Organo-silica Network Glasses and Nanocomposite Polymers

Andrews M.P., Belanger N., Manseau M.-P., Duxin N., Maron E., Lofgreen J., van Veggel F.C.J.M., McGill University, CA

This talk focuses on two classes of nanocomposite media that exhibit Light Induced Self Inscription. We describe LISI in sol-gel derived photosensitive glasses containing nanodispersions of zirconia, titania and noble metal nanoparticles. Waveguiding at 488 [...]

Highly Photo-Stable Type-I PbSe/SnSe and PbSe/SnS Colloidal Core/Shell Quantum Dots

Shan J., van Veggel F.C.J.M., Raudsepp M., Pattantyus-Abraham A.G., Young J.F., University of Victoria, CA

In an effort to improve photo-stability of IV-VI PbSe and PbS quantum dots (QDs) for application of infrared-based devices, we have synthesized type I core/shell colloidal QDs with PbSe and PbS as the cores, and [...]
