Multi-element signal enhancement mechanism investigation for laser ablation-assisted ultraviolet laser excited atomic fluorescence

Abstract

Multi-element detectable laser excited atomic fluorescence (LEAF) technique has been regarded as an impressive progress in analytical field because it possesses high sensitivity and overcomes the specific resonant wavelength constraint....

Atomic spectrometry update: review of advances in atomic spectrometry and related techniques

“…Ablation process, excitation process, and coupling behavior of multi-element detectable laser excited atomic fluorescence (LEAF) were investigated by Kou et al 127 Using a brass sample, LEAF was conducted by employing a 193 nm laser to intercept the ablated plasma generated with a Nd:YAG laser at 1064 nm. In particular, multi-element signals were significantly enhanced using low LA energy (1.49 mJ), which resulted in minimal sample destruction, and using an inter-pulsed delay of 200 ns.…”
