8.14.4.3.2 Monomer–excimer based sensing. An excimer is a complex formed between two fluorophore molecules of the same type—one in the excited state and the other in the ground state, typically by the π–orbital interaction. 91, 92 While the excimer formation is determined by excitation and local concentration of the fluorophore, its fluorescence properties are red-shifted …

An excimer refers to a new luminescent chemical species formed through a strong interaction between the ground state and excited state components of a ratiometric metal sensing system. It emits low energy fluorescence with broad and weak bands compared to monomers, and its formation is a reversible process.

Excimer lasers, also known as exciplex lasers, are a type of UV lasers used in the manufacturing of semiconductor-based integrated circuits, microelectronic devices, and micromachining. Excimer lasers have played a significant role in advancing laser processing techniques, particularly in the field of Nano-patterning.

The excimer lasers are pulsed lasers with typical pulse width of 20–40 ns. The pulse energies are usually in range 0.1–1 J. The excimer lasers are popular excitation source in organic photochemistry, since many compounds have absorption in the ultraviolet wavelength range, and no other lasers can emit directly in this wavelength range.

The excimer laser is capable of debulking both the atherosclerotic substrate and the thrombotic material within a CTO [18]. Clinically, the excimer laser has been found a useful interventional tool for targeted thrombus removal strategy [19]. The physical process caused by the laser activation is the creation of acoustic shock waves that ...

Nov 1, 2024 · Excimer light is a subtype of NB-UVB that emits a 308 nm wavelength that can provide targeted phototherapy treatment. 1, 13 The Food and Drugs Administration (FDA) approved the excimer light for the treatment of psoriasis, vitiligo, atopic dermatitis, and leukoderma, and has demonstrated efficacy in the treatment of other hypopigmented ...

For further practical application, research has been focused on exploring static excimer formation in rigid media by designing and regulating π–π stacking between molecules.64–77 Unlike a dynamic excimer, which is formed by initial excitation from a monomer, a static excimer can be generated by direct excitation from a pre-associated ...

Sep 1, 2024 · Excimer lasers typically possess high photon energies (6.42 eV for 193 nm ArF, 5.00 eV for 248 nm KrF), enabling them to directly break chemical bonds within a material's surface layer. When chemical bonds are broken faster than the rate of recombination, materials disintegrate into smaller entities like atoms, molecules, and ions.

Dec 1, 2024 · Both analyses have successfully identified three components attributed to monomer, w-excimer, and s-excimer species, which were additionally confirmed by TRES and FLIM measurements. The swelling by DMSO induced the expansion of the interlayer space facilitating the conversion of present species to w-excimers and s-excimers.

Dec 1, 2024 · The KrCl* excimer lamp is mercury-free and can emit UV photon (539 kJ∙Ein −1) with higher energy than UV254 (471 kJ∙Ein −1), which is expected to enhance photochemical processes. Thus, the UV222-based advanced oxidation processes are promising to fulfill the strict requests for technique efficacy of some application scenarios ...
