The role of mid-gap states in all-inorganic CsPbBr 3 nanoparticle one photon up-conversion Academic Article uri icon

abstract

  • CsPbBr3 nanoparticles that have been treated with NH4SCN to produce essentially trap-free surfaces show an increase of one photon up-conversion quantum yield with little change to the up-conversion energy of activation, as estimated using an Arrhenius analysis. This suggests that mid-gap trap states constitute a loss pathway, and may not be integral to the one-photon excitation mechanism.
