Trong nghiên cứu này, chúng tôi tiến hành chế tạo chấm lượng tử carbon (CDs) từ nút bấc bằng phương pháp thủy nhiệt. CDs chế tạo được có đường kính trung bình 6,2±2,7 nm. Phổ hấp thụ cho thấy, hai đỉnh ở vị trí 217 và 280 nm tương ứng với chuyển dời π-π* và n-π* của liên kết C=C và C=O...

In this study, we synthesised the carbon nanodots (CDs) from the waste wine cork using a hydrothermal method. The analysis results indicated the average diameter of CDs was 6.2±2.7 nm. The UV-vis absorption spectrum shows two peaks around 217 and 280 nm, which are attributed to π-π* transition and n-π* transition of the C=C and the C=O bonds, respectively...
