Journal ArticleDOI
Effect of synthesis conditions on the growth of ZnO nanorods via hydrothermal method
Dheerachai Polsongkram,Pattanasuk Chamninok,Supakorn Pukird,Lee Chow,Oleg Lupan,Oleg Lupan,G. Chai,Hani Khallaf,Sanghoon Park,Alfons Schulte +9 more
TL;DR: In this article, the effect of synthesis conditions on ZnO nanorod growth was systematically studied by scanning electron microscopy, showing that the morphology and ordering of ZnOs are determined by the growth temperature, the overall concentration of the precursors and deposition time.
Journal ArticleDOI
Luminescence properties of europium-doped cerium oxide nanoparticles: role of vacancy and oxidation states.
TL;DR: A simple chemical precipitation technique is reported to synthesize europium-doped cerium oxide nanostructures to enhance the emission properties, which showed an acute dependence on the concentration of oxygen ion vacancy and trivalent cerium, which, in turn, could be modified by dopant concentration and the annealing temperature.
Journal ArticleDOI
Synthesis and characterization of Cu-doped ZnO one-dimensional structures for miniaturized sensor applications with faster response
Lee Chow,Lee Chow,Oleg Lupan,Oleg Lupan,Guangyu Chai,Hani Khallaf,Luis K. Ono,B. Roldan Cuenya,Ion Tiginyanu,Ion Tiginyanu,Veaceslav Ursaki,Veaceslav Ursaki,V. Sontea,Alfons Schulte +13 more
TL;DR: In this article, the authors reported the hydrothermal synthesis at 95°C of Cu-doped ZnO low-dimensional rods for room-temperature (RT) sensing applications and enhanced sensor performances.
Journal ArticleDOI
Non-linear optical properties of chalcogenide glasses in the system As S Se
Thierry Cardinal,Kathleen Richardson,H. Shim,Alfons Schulte,R. Beatty,K. Le Foulgoc,C. Meneghini,J.-F. Viens,Alain Villeneuve +8 more
TL;DR: In this article, the effects of iso-structural substitution of Se for S and the resulting impact on structure and the non-linear refractive index, n 2, are discussed.
Journal ArticleDOI
Direct femtosecond laser writing of waveguides in As2S3 thin films.
Arnaud Zoubir,Martin Richardson,Clara Rivero,Alfons Schulte,Cedric Lopez,Kathleen Richardson,Nicolas Hô,Réal Vallée +7 more
TL;DR: The dependence of the index differential on the peak intensity reveals the nonlinear nature of the photosensitivity in arsenic trisulfide below its bandgap energy, and the refractive-index change is correlated to the photoinduced structural changes inferred by Raman spectroscopy data.
