| Abstract
| - Few-atom gold nanoclusters exhibit strong size-dependent fluorescence emission. For many applications, theseclusters are preferable to quantum dots or organic fluorophores as fluorescent labels. However, the publishedsynthetic procedures to create these nanoclusters involve toxic chemicals, are of low synthetic yield, andconcurrently produce large nanoparticles. Here, we report two methods for high-yield synthesis of goldnanoclusters, utilizing physiological temperature and green chemistry. Blue, green, and red emissive nanoclusterswith pH stability in a range of 6−8 were produced.
