We have constructed a high-efficiency, photon-counting phase-modulation fluorometer (PC-PMF) using a field-programmable gate array, which is a modified version of the photon-counting fluorometer (PCF) that works in a pulsed-excitation mode (Iwata and Mizuno in Meas Sci Technol 28:075501, 2017). The common working principle for both is the simultaneous detection of the photoelectron pulse train, which...
We construct a photon-counting, fluorescence lifetime measurement system with a channel width of 5.0 ps. This is a modified version of our previous fluorometer based on a simultaneous detection method of photoelectron pulse trains after pulsed excitation (Iwata in Meas Sci Technol 28:075501, 2017), which can accept multiple photons during a one period of the excitation for building a histogram. Although...
