The laser atomic fluorescence excitation and emission spectra ofsodium in an air-acetylene flame are shown below.. In the excitationspectrum, the laser (bandwidth = 0..03 nm) was scanned throughvarious wavelengths while the detector monochromator (bandwidth =1..6 nm) was held fixed near 589 nm..
Laser Induced Fluorescence (LIF) is an optical spectroscopic technique where a sample is excited with a laser, and the fluorescence emitted by the sample is subsequently captured by a photodetector.. LIF can be understood as a class of fluorescence spectroscopy where the usual lamp excitation is replaced by a laser source..
It is common to refer to the technique as excitation or emission LIF spectroscopy; Figure 1 illustrates this concept.. In the figure a laser is employed to excite molecules from their ground state into an electronically excited state.. As the molecules relax back into the ground state, fluorescence is detected by a photomultiplier tube (PMT)..
Laser-induced fluorescence (LIF) or laser-stimulated fluorescence (LSF)[1] is a spectroscopic method in which an atom or molecule is excited to a higher energy level by the absorption of laser light followed by spontaneous emission of light..[2][3] It was first reported by Zare and coworkers in 1968..[4][5] LIF is used for studying structure of ..
Laser Induced Fluorescence (LIF) is known to be a very sensitive and important tool for characterization for chemicals, bio-chemicals and biological tissues.. Most of the spectra are quite similar and it will be very difficult to identify them on the basis of single..
We present a theoretical model interpreting the experimental results observed under strong two-photon ns laser excitation of the 6S1/2 potassium atomic state, where emissions near the 6S1/2-4P3/2 ..
Otherwise, all the excitation peaks occur at higher frequencies or shorter wavelengths and all of the emission peaks occur at lower frequencies or longer wavelengths.. The spectra in Figure 3..4.. 6 show the excitation and emission spectra of anthracene.. Note that the only overlap occurs at 380 nm, which corresponds to the S 0 -S 1 transition..
Laser-induced fluorescence emission The mby fluorescence emission is induced by laser excitation and can be revealed through a monochromator and a CCD detector.. The wavelength and the power of the laser excitation are not restrictive at low pressure, and even few milliwatts of the 647..1-nm excitation line of a Kr ion laser can induce an easily detectable fluorescence emission..
The excitation spectrum is measured at a single emitted wavelength, whilst varying the wavelength of the excitation laser beam.. An emission spectrum works the other way around, measuring the ..
