Abstract: | Within the framework of the probability method, we obtained analytical expressions for the luminescence power, absorption
power, and energy yield of photoluminescence in a system of particles with three energy levels on periodic pulse excitation.
It is shown that at certain periods and durations of exciting pulses the energy yield can be higher than under stationary
excitation conditions.
