Synchronization of oscillatory chemiluminescence with pulsed light irradiation

► A chemical oscillator, H2O2-KSCN-CuSO4-NaOH system, was illuminated. ► The oscillatory behavior was influenced by the photo-irradiation. ► Response of the oscillator to the pulsed light irradiation was rapid. ► The luminol added chemical oscillator was also illuminated. ► Oscillatory chemiluminescence synchronized with pulsed light irradiation.
