Synthesis of quantum dot doped chalcogenide glasses via sol-gel processing

Semiconductor quantum dots (QDs) are used to dope wide-bandgap chalogenide glasses via sol-gel processing. Such chalcogenides enhance surface passivation of the quantum dots, as evidenced by the increased PL emissions of both core and core shell species used, while a ZnO glass leads to irreversible oxidation of the embedded quantum dots. The embedded QDs are photostable. (C) 2011 American Institute of Physics. [doi:10.1063/1.3579442]
