Abstract and subjects
A time-dependent likelihood distribution for analyzing time correlated single photon counting data from a four-pixel time-resolved single molecule localization microscopy experiment is discussed. It is generated by accounting for the probabilities to record photons from two emitters, background counts, and dark counts during two different time channels relative to each incident laser pulse in the experiment. Maximizing the distribution enables localization of each emitter in a dual emitting nanostructure based on the disparate photoluminescence lifetimes of the emitters, even when both emitters are simultaneously in an emissive state. The technique is demonstrated using simulated photon counting data from a hypothetical non-blinking dual-emitter nanostructure in which the distance between the two emitters is less than 10-nm.
