A versatile, low-cost, easy-to-implement, microprocessor-based scanning spectrophotometer suitable for time-resolved emission spectroscopy and time-correlated measurements is reported. Such a system, with high temporal and spectral resolution, incorporating pulsed lasers to excite the sample and with single-photon counting detection, has been used to investigate the photophysical properties of weakly emitting samples. This system is capable of measuring sub-nanosecond and nanosecond fluorescence lifetimes. Typical emission spectra are presented.
