✦ Synopsis

During the past decade many studies on speciation of actinides in natural and artificial environments have been carried out. High demands on the sensitivity in speciation of actinides lead to the development of advanced detection methods. This is connected with intensive use of laser systems as excitation sources. The laser can provide any wavelength from the near UV to the near infrared (NIR) wavelength range. The development of tunable solid-state lasers overcame some disadvantages of dye laser systems. The application of low temperatures for samples measured with fluorescence spectroscopic methods brought effort in the detection of carbonate species. The availability of modern femtosecond laser systems in combination with intensified charge coupled device (ICCD) cameras provided the possibility to exploit the fluorescence properties of aromatic organic compounds for the study of their interaction with actinides, especially non-fluorescent metal ions.
