Development of IR-emitting colloidal II-VI quantum-dot materials

摘要

The current state-of-the-art of colloidal II-VI nanocrystalnformation using the aqueous/thiol synthesis route is described. Work onnsingle component and heterostructures and mixed compound quantum dots isndiscussed. The purpose of the work is to provide a range of infraredn(IR)-emitting materials with high quantum efficiency (QE) as potentialngain media for future ultrawideband optical amplifiers for high-capacitynwavelength-division multiplexing (WDM) telecommunications systems.nPhysical and chemical factors influencing particle sizes are described
