Laser excited atomic and ionic fluorescence in an inductively coupled plasma
Abstract
The characteristics of atomic and ionic fluorescence excited by a pulsed dye laser in an inductively coupled plasma (ICP) and their application to plasma diagnostics have been investigated. The vertical distributions of atomic and ionic fluorescence for calcium and yttrium are directly obtained in the central region without the need of an Abel inversion procedure. Thermally assisted fluorescence intensities are found not to be in a Boltz mann distribution, despite the good linearity shown for the emission plot at the same wavelengths. The usefulness of the ICP as an atomization or ionization cell in fluorescence spectrometry is also discussed. However. fluorescence detection limits in the analytical region of the plasma are about two orders poorer than those for emission
