Bright-field TEM images of two different nanocrystals in (a). Spatially integrated CL spectrum (with a spectral resolution) and the decomposition into Gaussian components in (b), as previously described in Ref. 10. SEM image of the region over which the spatially integrated CL spectra and monochromatic CL images were acquired in (c). A composite CL image that maps the emission of groups of nanocrystals that possess similar peak emission wavelengths in (d).
A stack plot of CL spectra acquired by local excitation of nanocrystals at various temperatures in (a). A semilog plot of vs is shown as an inset. CL spectra acquired for local excitation of a similar group of nanocrystal for various beam currents in (b).
CL intensity vs time transients for various wavelengths for local excitation of a group of nanocrystals in (a). CL decay time vs wavelength for various temperatures in (b).
Time delayed CL spectra for the local excitation of a group of nanocrystals at temperatures of 60 K (a) and 90 K (b). Various time windows D1-D7 reveal snapshots of the CL spectrum during the decay.
