Talk:fluorescence

IN XRAY FLUORESCENCE SPECTROMETRY WE TALK ABOUT SECONDARY FLUORESCENCE.WHAT EXACTLY MEANS THE PRIMARY FLUORESCENCE IN TERMS OF XRAY FLUROSCENCE SPECTROMETRY

OK it seems like primary fluorescence (autofluorescense) is produced by substances already present in the material being examined, while secondary fluorescence is produced by substances that have been deliberately introduced. But don't quote me. See http://www.olympusconfocal.com/theory/glossary.html Kappa 05:51, 17 May 2008 (UTC)
