Single photon emitters based on InP/GaInP quantum dots have been studied under p-shell excitation by time-resolved photoluminescence and photon correlation spectroscopy. By tuning the excitation energy in resonance with quantum dot excited states, we observe a marked decrease of the antibunching time as a result of the increased excitation rate for decreasing energy detuning. A similar behavior is observed by increasing the pump power. The spectral dependence of the antibunching rate follows the energy profile of the excited state, as measured by photoluminescence excitation.
