Abstract

Full control in size distribution and surface chemistry of Si nanocrystals (NCs) allows the high efficiency of visible light emission. The NC synthesis and subsequent surface modification with organic monolayers are performed in a single step by laser chemical method. Interestingly, it is found that the distinct emission in the green and blue range arises from the difference in NC size and molecular coverage of the monolayers.
