Investigation of oxygen influence to the optical properties of tirapazamine [PDF]
Journal of Molecular Modeling, 2022 Abstract New data on 3-amino-1,2,4-benzotriazine 1,4-dioxide (tirapazamine) fluorescence has been obtained using the Perkin–Elmer UV-vis-NIR spectrophotometer Lambda 950 experimental technique in combination with the extensive DFT-theory approach.

Optical investigations of the states in GaP:Ni
Journal of Physics C: Solid State Physics, 1982 This paper reports photoconductivity measurements of semi-insulating Ni-doped GaP materials. The photoresponse spectra obtained exhibit strong onsets at 0.62 eV and 0.95 eV, as well as a number of weaker features. Optical transitions are interpreted as between Ni3+ and Ni2+ ions, and the conduction and valence bands, as well as transitions involving a ...

Optical-acoustic effect in laser optics investigations [PDF]
Revue de Physique Appliquée, 1990 Parameters of the acoustic signals (AS) excited in the massive Al, Be and Cu mirrors by TEA CO2- and Nd : glass-laser pulses were investigated. Correlations between the AS parameters and an emergence of different types of laser-induced damage such as evaporation of heat insulated defects, melting and optical breakdown off irradiated surface have been ...

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]
, 2007 The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence
