Matrix Effect of Akali and Alkaline Earth Metal Halides on Fluorescence Quantum yield of Indium in Laser-induced Fluorescence Flame Spectrometry

摘要

As interfered with by alkali and alkaline earth metal halidesadded as the matrix in an acetylene/air flame, the fluorescencequantum yield of In as the analyte in a laser-induced fluorescence(LIF) flame spectrometry has been thoroughly characterized. Thefluorescence quantum yield is determined by a ratio of F to A, whereF is the measured fluorescence of In and A is the difference betweenthe absorption signals recorded for the analyte and the blanksolutions.
