| dc.description.abstract | New type of nanocomposite (NC) films have been fabricated on the basis of π-conjugated oligomer poly-(N-epoxypropyl)carbazole (PEPC) as polymeric matrix and organic compound Cobalt phthalocyanine (CoPc) NC as photochromic dye, and investigated. Thin layers of NC with different concentrations of CoPc in NC (0.2, 1, 3, 6, 9, 12 % of mass) on glass substrates from chemical solutions were deposited. The sizes of CoPc nanoparticles were less than 100 nm. Complex investigation of optical and photoluminescence properties allowed us to determine 3 absorbtion bands: the absorption band that appears in the region of 315–350 nm and verifies π→π* transition for the Soret band B band gap; and n→π* bands appeared at about 600–735 nm for the Q1 and Q2-band. The effect of IR shift of NC under UV irradiation on absorption was observed. | en_US |
