ACS Appl Mater Interfaces. 2016 Dec 21. doi: 10.1021/acsami.6b12859. [Epub ahead of print]Sonication induced vertical fragmentation of two-dimensional (2D) WS2 nanosheets into highly luminescent, monodispered, zero-dimensional (0D) quantum dots (QDs) is reported. The formation of 0D structures from 2D sheets and their surface/microstructure characterization are revealed from their microscopic and spectroscopic investigations. Size dependent optical properties of WS2 nanostructures have been explored by UV-vis absorption and photoluminescence spectroscopy. Read More
