A (13,3) nanotube is measured with V_a=+1.2 V, V_b=−1.8 V and f=5,011 Hz. The spectral integration window for I_PL is from λ_em=1,440 to 1,490 nm. (a,b) Time dependence of gate voltage and integrated PL, respectively. (c) Integrated PL as a function of time and τ. (d) Temporal evolution of integrated PL for τ=50, 100 and 150 μs. For b–d, P=50 μW is used. (e) Integrated PL as a function of time and P. (f) Laser power dependence of pulse width.
