In the report, microwave-assisted and hydrothermal methods were adopted respectively to produce nitrogen doped carbon dots (N-CDs) using ginkgo fruits as the sole carbon source without additional surface passivation agents. The differences between these two N-CDs were compared in luminescence properties, particle sizes and morphologies. The TEM images showed that both microwave-assisted N-CDs (M-N-CDs)...
In this study, double shelled NIR CdSeTe/CdS/C quantum dots (QDs) were synthesized by a liquid phase method. The as-prepared QDs showed low cytotoxicity and good biocompatibility due to the formation of carbon shell. The imaging of targeted Human cervical carcinoma cells (HeLa cells) indicates that the CdSeTe/CdS/C QDs have excellent optical properties and cell viability. These results clearly shows...
