Fluorescence detection is classically achieved with a solid state detector (SSD) on x-ray absorption spectroscopy (XAS) beamlines. This kind of detection however presents some limitations related to the limited energy resolution and saturation. Crystal analyzer spectrometers (CAS) based on a Johann-type geometry have been developed to overcome these limitations. We have tested and installed such a system on the BM30B/CRG-FAME XAS beamline at the ESRF dedicated to the structural investigation of very dilute systems in environmental, material and biological sciences. The spectrometer has been designed to be a mobile device for easy integration in multi-purpose hard x-ray synchrotron beamlines or even with a laboratory x-ray source. The CAS allows to collect x-ray photons from a large solid angle with five spherically bent crystals. It will cover a large energy range allowing to probe fluorescence lines characteristic of all the elements from Ca (Z = 20) to U (Z = 92). It provides an energy resolution of 1-2 eV. XAS spectroscopy is the main application of this device even if other spectroscopic techniques (RIXS, XES, XRS, etc.) can be also achieved with it. The performances of the CAS are illustrated by two experiments that are difficult or impossible to perform with SSD and the complementarity of the CAS vs SSD detectors is discussed.

This review covers the approximately two-year period since our last review (A1), roughly from January 2004 through December 2005. A computer search of Chemical Abstracts provided most of the references for this review. Other citations were found through individual searches by the various authors who wrote a particular section of this review. In an effort to more effectively accomplish this goal, we have included authors who are experts in the various subtopics of this review. Coverage is limited to articles that describe new developments in the theory and practice of molecular luminescence for chemical analysis in the ultraviolet, visible, and near-infrared region.Citations may be duplicated between sections due to articles with contents that span several topics. However, in an effort to reduce the length of this review, we have attempted to limit this kind of duplication. In general, citations are limited to journal articles and usually do not include patents, proceedings, reports, and dissertations.We have tried to focus on important advances of general interest and relevance to the field of analytical chemistry, rather than extensions of previous advances. This was done in an effort to continue our recent attempts to significantly reduce the length of this biennial review. In addition, we have also expanded our description of individual citations for better clarification of content where necessary.Although we are not able to provide extensive coverage of developments of relevance to broad areas such as chromatography and biological sciences, we have tried to include major review articles and chapters relevant to these topics. If you feel that we omitted an important article published during the above referenced time period, please forward the reference to one of us and we will be certain to consider it for the next review.
