New chemistry has been developed to integrate lead chalcogenide nanocrystals into continuous inorganic matrices of chalcogenide glasses. Inorganic capping, rather than conventional organic capping ligands, allows simple and low-temperature encapsulation of these nanocrystals into solution-cast infrared (IR)-transparent amorphous As2S3 chalcogenide matrices. The resulting all-inorganic thin films display stable infrared luminescence in the technologically important near-IR region.
