FIG. 1.

Calculated emission spectra of , , , , and at room temperature (solid lines) and at (dashed lines). The center plot also shows the calculated, low-temperature absorption spectrum (dashed line). “A” peaks originate from recombination of an electron in an -like state with a hole in an -like-state, while “B” peaks originate from the recombination of a electron with a hole (see text). For clarity purposes, the room-temperature spectra have been shifted rigidly on the axis to align the peaks with those of the low-temperature spectra. All spectra were broadened using a Gaussian with a width.

Origin of main peaks observed in the emission spectra of Fig. 1. Column 3 shows the shift of each peak with respect to peak “a” of the absorption spectrum. Column 4 shows the main optical transition responsible for each peak. Boldface characters indicate the single-particle states occupied by the electron and the hole that recombine.
