报告摘要：

Among the variety of semiconductor quantum dots targeted for applications in optoelectronics, biological imaging and chemical sensing, silicon nanocrystals (ncSi) are drawing increasing attention because of their earth-abundance, low cost, and purported lack of toxicity. To synthesize freestanding ncSi, we employed several methods that could all yield hydride-terminated ncSi and which allow further surface functionalization and chemical reactions. These works provide opportunities for applications of size-selected near infrared emitting ncSi in biomedical imaging, photothermal therapy, and CO2 reduction for the production of chemicals and fuels. Other exciting reactions of ncSi and the synthesis of composites are also being explored.
