• The electron--hole liquid (EHL) and electron--hole plasma (EHP) luminescence bands have been found to have an exponential tail given by \exp(h\nu/E_{\text{e}}) on the low-energy side. The tail parameter E_{\text{e}} remains at 29 meV in the EHL temperature range, while it increases with temperature in the EHP and attains 75 meV at 480 K. The E_{\text{e}} in the EHL temperature range is explained by the random potential fluctuation due to the random arrangement of electrons and holes at high density. The E_{\text{e}} increasing with temperature in the EHP is explained by the dynamic random potential fluctuation due to the Brownian motion of electrons and holes accelerated thermally.
