Thin luminescent films of TiO2 : Sm were prepared by sol-gel-method using spray pyrolysis technique. Various techniques (includind IR absorption, Raman, AFM, XPS, photoluminescence) were to characterize the samples. After a thermal treatment up to 750◦C, an intense Sm luminescence with a well-resolved fine structure was observed under optical excitation(More)
The chemical spray pyrolysis method was used to deposit CuInS2 (CIS) thin films and Au nanoparticles (NPs) in two configurations: glass/Au-NP layer covered with CuInS2 film (Au-NP/CIS) and glass/CuInS2 films covered with Au-NP layer (CIS/Au-NP). According to X-ray diffraction (XRD), the spray of 2 mM HAuCl4 aqueous solution with a volume of 2.5 to 15 ml(More)
