TUNABLE ORGANIC DYE LASER AS AN EXCITATION SOURCE FOR ATOMIC-FLAME FLUORESCENCE SPECTROSCOPY

Abstract
A laser‐pumped tunable organic dye laser is shown to excite atomic‐flame fluorescence of the 5535. 5‐Å barium resonance line. Ultrasonic nebulization reduces light scattering, producing a straight‐line analytical working curve suitable for quantitative analysis.
