Hasnaa El Ouazzani,Konstantinos Iliopoulos,M. Pranaitis,Oksana Krupka,Vitaliy Smokal,Aleksey Kolendo,Bouchta Sahraoui +6 more
TL;DR: This work investigates the second- and third-order nonlinear optical response of spin-deposited thin films of three different push-pull side chain azobenzene polymers with strong dependence upon the structure of the systems, which is related to the different charge transfer within the molecules.
Journal ArticleDOI

TL;DR: In this article, the results of the nonlinear optical (NLO) investigation (second and third harmonic generation) of spin deposited high-quality thin films of styrylquinoline containing methacrylic polymers studied by using Maker fringes technique employing 30 ps laser pulses at fundamental wavelength of 1064
Journal ArticleDOI
Optical properties of disperse dyes doped poly(methyl methacrylate)
Beata Derkowska-Zielinska,Oksana Krupka,Vitaliy Smokal,Andrzej Grabowski,M.K. Naparty,Lukasz Skowronski +5 more
TL;DR: In this paper, the linear optical properties such as absorption coefficient, refractive index and energy band-gap of guest-host polymeric thin films were studied using spectroscopy and spectroscopic ellipsometry combined with transmittance measurements.
