(a), (b), (c), and (d) are temperature-dependent CL spectra of the corresponding samples (a)–(d). The electron beam voltage is 8 kV and the beam current is 600 pA. The temperature at which the spectrum was obtained is indicated in ascending order in each figure, corresponding to the top-down sequence of the CL peak. The vertical scale of the 300 K spectrum is multiplied by a number shown beside the spectrum in each figure.
