    • E. V. Tsiper, Phys. Rev. B 54, 1959 (1996). In Tsiper’s model, it is asserted that emission from the lowest excitonic state (Formula presented) cannot be measured technically when this state is resonantly excited since the emission is masked by the excitation laser beam. Emission from (Formula presented) is seen in his model only when a higher (Formula presented) state is excited. Hence the redshift is simply (Formula presented) This model overlooks the fact that even in a dot, state (Formula presented) has a finite (although narrow) spectral width, so one can tune the absorption to occur at a slightly different wavelength from the emission. Furthermore, time-resolved experiments avoid the technical difficulty of “masking” by using fast excitation pulses that vanish long before the emission occurs. Finally, Tsiper’s model does not explain the issue of the observed long lifetime of the lowest emitting state.
