3.4: Excitation and Emission Spectra
What would be the difference between an excitation and emission spectrum in fluorescence spectroscopy? In an excitation spectrum, the emission monochromator is set to some wavelength where the sample is known to emit radiation and the excitation monochromator is scanned through the different wavelengths.
Fluorescence Excitation and Emission Fundamentals
of the ground state, and thus, excitation processes usually originate from this energy level. The category of molecules capable of undergoing electronic transitions that ultimately result in fluorescence are known as fluorescent probes, fluorochromes, or simply dyes.
Why AI and energy are the new power couple – Analysis
However, data is not systematically collected on AI''s energy use and wider environmental impacts, and there is a need for greater transparency and tracking – especially as models grow. The most efficient computing infrastructure and AI algorithms should be prioritised to prevent it from offsetting efficiency gains.
Excitation Energy
The concept of mean excitation energy as the ability of a medium to absorb energy from any kind of incident radiation (either photons or charged particles) found its origins in the pioneering work by Niels Bohr in his classical theory of penetration of swift charged particles in matter 1–3 whereby the absorbed energy was envisaged as a sum of contributions …

Fluorescence Excitation & Emission
There is usually an overlap between the higher wavelength end of the excitation spectrum and the lower wavelength end of the emission spectrum. In fluorescence microscopy, this overlap of excitation and emission intensities and wavelengths (Figure 1(c)) must be eliminated by selecting the appropriate excitation filter, beamsplitter ( reflected light …
