Ternary I-III-VI2 nanocrystals(NCs),such as AgInS_(2) and CuInS_(2),are garnering interest as heavy-metal-free materials for photovoltaics,luminescent solar concentrators,LEDs,and *** origin of the emission and absorption properties in this class of NCs is still a subject of *** theoretical and experimental studies revealed that the characteristic Stokesshifted and long-lived luminescence of stoichiometric CuInS_(2) NCs arises from the detailed structure of the valence band featuring two sublevels with different *** same valence band substructure is predicted to occur in AgInS_(2) NCs,yet no experimental confirmation is available to ***,we use complementary spectroscopic,spectro-electrochemical,and magneto-optical investigations as a function of temperature to investigate the band structure and the excitonic recombination mechanisms in stoichiometric AgInS_(2) *** transmission measurements reveal the signatures of two subbands with opposite parity,and photoluminescence studies at cryogenic temperatures evidence a dark state emission due to enhanced exchange interaction,consistent with the behavior of stoichiometric CuInS_(2) *** the temperature as well as applying reducing electrochemical potentials further suppress electron trapping,which represents the main nonradiative channel for exciton decay,leading to nearly 100%emission efficiency.
