Abstract
A versatile, low-cost, easy-to-implement, microprocessor-based scannin g spectrophotometer suitable for time-resolved emission spectroscopy a nd time-correlated measurements is reported. Such a system, with high temporal and spectral resolution, incorporating pulsed lasers to excit e 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 fl uorescence lifetimes. Typical emission spectra are presented.
