【Abstract】 New strategies for materials fabrication are of fundamental importance in the advancement of science and technology. Organometallic and other organic solution phase synthetic routes have enabled the synthesis of functional inorganic quantum dots or nanocrystals. These nanomaterials form the building blocks for new bottom-up approaches to materials assembly for a range of uses; such materials also receive attention because of their intrinsic size-dependent properties and resulting applications. Here we report a unified Liquid-Solid-Solution strategy to the synthesis of a large variety of nanocrystals with different chemistries and properties and with low dispersity. This strategy is based on a general phase transfer and separation mechanism occurring at the interfaces of the liquid, solid and solution phases present during the synthesis. Despite the diversity in crystals structures and properties, we have succeeded in preparing nearly all the functional nanocrystals / nanospheres with controllable size and surface properties, which show the possibilities of the final establishment of a general methodology to low-dimensionality nanostructures and will arouse some new opportunities to nano-related fields.
