Optical properties of doped polycarbonate layers

Optical properties of polycarbonate layers doped with triphenylamine and ch lorotricarbonyl diimine rhenium complex have been investigated, The samples have been prepared by spin coating on quartz glass and indium tin oxide (I TO) coated glass substrates. Root mean square surface roughness of the film s obtained by atomic force microscopy is low (similar to3 Angstrom). Optica l functions of ITO and doped polymer layer for two different dopant concent rations have been determined by spectroscopic ellipsometry in the spectral range from 1.55 to 4.1 eV. The absorption spectra of the chlorotricarbonyl diimine rhenium complex dissolved in chloroform and toluene have also been measured. (C) 2001 Elsevier Science B.V. All rights reserved.
