In this investigation, Ag@TiO2 nanocomposite was prepared by deposition of silver nanoclusters onto commercial TiO2 nanoparticles (known as P25 TiO2) via photodeposition technique as clean and simple photochemical route. The synthesized Ag@TiO2 nanocomposite was utilized in the fabrication of dye-sensitized solar cell (DSSC) chiefly because, compared ...

The series of three donor-spacer-acceptor complexes, DPAF-Ptn-NDI, has been synthesized and characterized using time-resolved absorption spectroscopy. In these complexes, the donor is a (diphenylamino)-2,7-fluorenylene (DPAF) unit, the acceptor is a naphthalene diimide (NDI), and the spacers are a series of platinum acetylides of varying lengths, [-Pt(PBu(3))(2)-C≡C-Ph-C≡C-](n) (where Bu = n-bu...

The signal charge loss due to initial recombination and that due to volume recombination have been measured separately using parallel plate ionization chambers irradiated with cobalt60 gamma rays, over a wide range of applied voltage and air humidity. It is shown that both initial and volume recombination depend on the electric field strength and also on humidity through ion clustering reaction...
