We develop a theory of secondary emission from a single quantum dot, when the lowest-energy states of its
electron–hole pairs are involved in the photoluminescence process. For the sake of definiteness, our model allows
for two states contributing to the luminescence. We analyze the dependency of secondary emission intensity on
the energy gap between the states, while considering that the gap is determined by the quantum dot’s size. An
analytical expression for the time-dependent signal of thermalized luminescence is obtained using an analytical
solution to the kinetic Pauli equation. This expression yields the signal of stationary luminescence as the spectral
width of the excitation pulse tends to zero.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE). Downloading of the abstract is permitted for personal use only.
