We define a new characteristic photon energy for the Band function, E{sub wz}, and describe a new way of estimating the peak luminosity of the prompt emission from GRBs, L{sub iso}, which is not dependent on the time binning. We show that E{sub wz} and L{sub iso} are correlated for all bursts, long and short. The new photon energy-luminosity relationship gives us a strong indication that the underlying process responsible for the prompt GRB emission is thermal.
