摘要：

We have synthesized ZnS/CdSe/ZnS quantum dot quantum well (QDQW) by using a microfluidic reactor. The synthesized QDQW emitted blue fluorescence and the quantum yield was achieved at 50%. Furthermore, we were able to tune the photoluminescence wavelength while maintaining the full width at half maximum (FWHM) by controlling the flow rate in CdSe layer deposition process. Our results demonstrate that high quality CdSe phase was embedded in the ZnS core and shelf, and the layer thickness was controlled homogeneously by using the microfluidic system. So, this system is considered as a useful tool for controlling the multilayer nanocrystals such as QDOW.
