摘要: Core-shell structure CdSe/HgSe/CdSe quantum dot well (QDQW) nanocrystals were firstly synthesized and controlled by colloidal chemical methods. High-resolution transmission electron microscope (HRTEM) photographs show that the CdSe core has a wurtzite crystal shell of HgSe hexagonal structure. The enhancement blue shift photoluminescence (PL) peak was observed which attributed to confinement effect carriers in well.
