Exciton trapping is responsible for the long apparent lifetime in acid-treated
Here, we show that deep trapped “dark” exciton states are responsible for the surprisingly long lifetime of band-edge photoluminescence in acid-treated single-layer MoS₂. Temperature-dependent transient photoluminescence spectroscopy reveals an exponential tail of long-lived states extending hundred...
