Figure 4
Non-classical EL emission.
(a) PL (λ = 532 nm excitation) and (b) EL (240 V bias) spectra acquired from the bright spot in the gray square in Fig. 3b. (c) Reference EL spectrum acquired at 500 V applied bias from an “optical grade” device fabricated with a 6 MeV C3+ microbeam. (d) CN(t) curve acquired from the black circled spot in Fig. 3b. The curve is not corrected by background removal.
