Journal ArticleDOI
Two-way diffusion model for short-exposure holographic grating formation in acrylamide-based photopolymer
TL;DR: In this paper, a theoretical model for the formation of a short-exposure holographic grating is presented, which accounts for both monomer and polymer diffusion and distinguishes between short polymer chains capable of diffusing and long polymer chains that are immobile.
Journal ArticleDOI
Optical characterization of sol–gel derived Nb2O5 thin films
TL;DR: In this paper, the optical properties of thin Nb2O5 films, obtained by spin coating of Nb sol on glass and silicon substrates, were investigated using nonlinear curve fitting.
Journal ArticleDOI
Vapor responsive one-dimensional photonic crystals from zeolite nanoparticles and metal oxide films for optical sensing.
Katerina Lazarova,Hussein Awala,Sébastien Thomas,M. Vasileva,Svetlana Mintova,Tsvetanka Babeva +5 more
TL;DR: The preparation of responsive multilayered structures with quarter-wave design based on layer-by-layer deposition of sol-gel derived Nb2O5 films and spin-coated MEL type zeolite is demonstrated and the quasi-omnidirectional photonic band is predicted theoretically, and confirmed experimentally by reflectance measurements at oblique incidence with polarized light.
Journal ArticleDOI
Structural and optical characteristics of tantalum oxide grown by pulsed Nd:YAG laser oxidation
TL;DR: In this paper, the effect of the substrate temperature (250-400°C) during oxidation and its optimization with respect to the used laser beam energy density (3.2-3.4J∕cm2 per pulse) is discussed.
Journal ArticleDOI

Y. C. Su,Chung Chin Chiou,Vera Marinova,Vera Marinova,Shiuan-Huei Lin,N. Bozhinov,Blagoy Blagoev,Tsvetanka Babeva,Ken-Yuh Hsu,Dimitre Dimitrov +9 more
TL;DR: In this paper, aluminum-doped zinc oxide (AZO) layers are prepared by using atomic layer deposition technique and obtained layers possess high optical transmittance at visible and near-infrared spectral range.
