We study the transient photoluminescence (PL) of photoexcited metals by solving the Boltzmann equation considering the effects of electron-electron and electron-phonon (e-ph) collisions where the e-ph coupling function is calculated from first principles in order to account for the energy transfer rate between electrons and phonons accurately. We apply the present scheme to the transient PL of silver and demonstrate that the agreement between the theory and the experiment is good where the effect of nonequilibrium electron distribution is significant to fit the experimental data.
