Synthesis and characterization of AgGaS2 nanoparticles: a study of growth and fluorescence.

Silver gallium sulfide nanocrystals were synthesized and characterized by fluorescence, TEM, EDS, and XRD to better understand the material system with an ideal band gap of 2.7 eV. The crystals were found to nucleate in the monoclinic structure, and develop two fluorescence peaks (650, 460 nm) influenced by stoichiometry.
