“…To establish independence of the phosphorescence decay time on the excitation pathway (2P vs 1P), the probe solution in a quartz optical cell (1cm path length) was placed in a temperature controlled chamber (Quantum Northwest) and excited by short ( 1ms-long) pulse trains from the laser at the wavelength matching the probe’s 2PA maximum…”
