An inexpensive, simple (but highly automated) instrument for acquiring high-resolution fluorescence and phosphorescence spectra of polycyclic aromatic hydrocarbons (PAHs) is described. Fluorescence and phosphorescence signals are processed by gated integration and photon counting, respectively. The instrument can be used to acquire excitation as well as emission spectra in both the frequency and time domain. In addition, a method for measuring single and double exponential phosphorescence decay times is presented. Decay times ranging from 0.3 ms to 300 ms were measured for several naphthalene derivatives, with a precision of approx.10%. The primary advantages of this instrument are high sensitivity, high selectivity, wide linear dynamic ranges, and a versatile range of applications.
