From: High–temperature droplet epitaxy of symmetric GaAs/AlGaAs quantum dots

Normalized low-temperature ensemble PL spectra of the samples L1C, H1C and H4C (from top down) capped with a barrier layer. The arrows mark the emission wavelength calculated using realistic dot shapes from AFM images taken from the corresponding uncapped samples and linear dimensions given by average values from the experimental size distribution.
