The surface defect dependent fluorescence is investigated by these charge-separated, similar sized, and various fluorescence colors emitted CDs. By investigating the reduced CDs by hydrothermal method, the size effect determined fluorescence is also proved. Citing Literature Volume17, Issue2February 2015Pages 138-142 RelatedInformation
