Summary form only given. In this paper, cerium-doped zinc oxide films (ZnO:Ce) were deposited by reactive chemical pulverisation spray pyrolysis technique using zinc and cerium chloraids as precursors at temperatures up to 500 /spl deg/C. The effect of Ce concentration on the structural, electrical and optical properties of ZnO thin films were carefully(More)
We have investigated the linear and nonlinear optical properties of high quality cerium-doped zinc oxide films (ZnO:Ce). The layers were grown by the reactive chemical pulverization spray pyrolysis technique using zinc and cerium chlorides as precursors at temperature up to 450/spl deg/C. The influence of Ce concentration on the structural, linear and(More)
Photoluminescence properties under different excitation and optical constants like refractive index, extinction coefficient, layer thickness of tris (8-hydroxyquinoline) aluminum(III) (Alq3) layers are studied in this paper. Measurements were carried out at different temperatures (15K – room temperature) and at wavelength range from 400 to 1200 nm for(More)
A photoluminescence (PL) study has been performed from 10 to 330 K on a 3,4:9, 10-perylenetetracarboxylic dianhydride (PTCDA) and aluminum tris (8-hydroxyquinoline) (Alq3) thin layers, grown on Si substrates by thermal evaporation. The observed anisotropy of the excitation energies, the spectral shape and the dispersion indicates the presence of two types(More)
This paper is concerned with the photoluminescence (PL) study of poly(N-vinylcarbazole) (PVK) thin films deposited on the glass substrate by the dip-coating method. The PL spectra have been measured under steady state excitation (He-Cd laser, 325 nm) in the temperature range from 13 to 300 K. All the samples being studied exhibit strong luminescence in(More)
