Physical and optical properties of phthalocyanine doped inorganic glasses

Physical and optical properties of various free base and metallic phthalocyanine (Pc) doped glass matrix are reported for the first time. Absorption spectral measurements of H2Pc, MnPc, NiPc, CoPc, CuPc, MoOPc, ZnPc and FePc doped borate glass matrix have been made in the 200-1100 nm region and the spectra obtained are analyzed in the 2.1-6.2 eV region to obtain the optical band gap (E-g) and the width of the band tail (E-t). Other important optical and physical parameters viz. refractive index (n), molar extinction coefficient (epsilon), density (rho), glass transition temperature (T-g), molecular concentration (N), polaron radius (r(p)), intermolecular separation (R), molar refractivity (R-m) are also reported.
