Fig. 4: Single-photon emission from ELM-QDs.
From: Efficient single-photon emission via quantum-confined charge funneling to quantum dots
a PL spectrum of the ELM-QD in Fig. 3a (ELM-QD 1) pumped with the excitation power of 100 nW. b Pump power dependence of the peak PL intensity from ELM-QD (blue) and o-QD (red). c Second-order correlation function, g(2)(τ), for photon emission from ELM-QD 1. Data points are fitted with an exponential decay function, \(y(\tau )=1-A\exp (-\varGamma \tau )\), where A = 0.96 and. \(\varGamma\) = 5.1 GHz: Inset: filtered ELM-QD PL spectrum.
