Photoluminescence is currently one of the major growth areas in spectroscopy - a situation made possible by the recent developments in analytical instrumentation and sample handling. These advances are outlined and put into context with the underlying theory. An introduction to the basic principles of photoluminescence, instrumentation and quantitative aspects of the technique is provided. In all cases, theoretical aspects are kept as simple as possible. A survey of the methods available for both organic and inorganic analytes using natural fluorescence or the formation of fluorescent derivatives is also included. This title will be of particular interest to all those wishing to update themselves on this advancing topic.
