Experimental techniques of luminescence spectroscopy take into consideration specific features of the field: very low level of the detected light and requirement of not-extremely high spectral resolution. Physical principles and modes of operation of photon detectors used in luminescence spectroscopy are discussed (photomultiplier tubes, avalanche photodiodes and CCD detectors). Basic constructions of spectral devices (monochromators and spectrographs) and their important parameters (dispersion, resolving power, and throughput) are introduced and analyzed. Two signal detection methods are described: phase-synchronous (lock-in) technique and photon counting. Experimental conditions imposed to acquire spectra with high signal-to-noise ratio are examined. Corrections to be applied to spectra owing to spectral sensitivity of the detection channel and monochromator slits opening are considered. Finally, methods and apparatus for time‐resolved luminescence measurements are introduced (the phase-shift method, time‐correlated photon counting, and boxcar integrator). The exposition throughout the chapter is illustrated by selected examples of experimental curves.

Keywords:   photon detectors, CCD detectors, monochromators and spectrographs, resolving power and throughput, lock-in technique, photon counting, signal-to-noise ratio, corrections to spectra, time-correlated photon counting, boxcar integrator
