Photophysics and Photochemistry of Naphthoxazinone Derivatives [PDF]
The Journal of Organic Chemistry, 2008 The photophysics and photochemistry of a series of naphthoxazinones have been studied using a combination of methods ranging from steady-state and time-resolved spectroscopic techniques to product analysis. The photophysics of naphthoxazinone derivatives is very dependent on the structure: phenanthrene-like compounds exhibit higher fluorescence quantum

A Thorough Understanding of Methylrhodium(III)–Porphyrin Photophysics: A DFT/TDDFT Study [PDF]
MoleculesRhodium–porphyrin complexes are characterised by their ability to activate C-H and C-C bonds and, therefore, find applications in synthesis and catalysis. Axial rhodoporphyrin ligands are susceptible to photodissociation under the influence of light. DFT

Harmonic vector noise-like square pulse in an Er/Yb co-doped fiber laser
Results in Optics, 2023 Vector noise-like square pulse (NLSP) has been experimentally observed in an Er/Yb co-doped figure-eight fiber laser. The energy of a single NLSP at the fundamental repetition rate reaches 346.6 nJ.

Photochemistry and Photophysics of Thienocarbazoles¶ [PDF]
Photochemistry and Photobiology, 2003 Two methylated thienocarbazoles and two of their synthetic nitro-precursors have been examined by absorption, luminescence, laser flash photolysis and photoacoustic techniques. Their spectroscopic and photophysical characterization involves fluorescence spectra, fluorescence quantum yields and lifetimes, and phosphorescence spectra and phosphorescence ...
