Abstract

The optical properties of two bulk nanocrystal (NC) systems, namely Ag 2S and EuS, were analyzed. A novel solvent-free method was used to synthesize Ag2S nanoparticles whereas thermal decomposition of a single-source precursor was used to synthesize EuS nanoparticles. The particle size distribution of both the Ag2S and EuS nanoparticles were characterized through transmission electron microscopy (TEM). It was found that nanocrystals, which can be potentially mistaken for quantum-confined structures on the basis of anomalous absorption spectra, does not only apply to EuS. The results show that these two bulk nanocrystal systems can occupy a complementary role to quantum confined structures as another building block for the development of new technologies.
