Show affiliationsEllipsometric parameters of a series of spin-coated thin films of palladium phthalocyanine derivatives with bromine and tetraalkoxyl substitutes (PdPc(OC8H17)4Brm, m = 0,2,3,4) are determined from a rotating analyser-polarizer type of scanning ellipsometer. The optical, dielectric constants and absorption coefficients of the films in the 500-800 nm wavelength region are reported. The results show that refractive index N (N = n-k), dielectric constant ε (ε = ε1-ε2) and absorption coefficient α in the region 500-800 nm are influenced by bromine atom substituted on the conjugated phthalocyanine ring regularly. It is found that there is approximately a linear relationship between the resonance absorption wavelengths of the films and the number of bromine atoms substituted on the phthalocyanine ring.
