Paper Abstract

Propyl ammonium bromide C3, carbazole-linked and naphtalen-linked ammonium bromides CBz and Nap, and PbBr2 Pb were dissolved in dimethylformamide (DMF) at the molar ratio of C3:CBz:Pb and C3:Nap:Pb = 2:0:1, 4:2:3, 1:1:1, 2:4:3, and 0:2:1. The thin films were prepared on fused quartz substrates by spin-coating from the DMF solutions. Super layer structure, where organic dielectric layer, inorganic semiconductor layer, and organic semiconductor are assembled in order, was successfully constructed by a simple spin-coating with the solution in which propyl ammonium bromide C3, carbazole-linked propyl ammonium bromide CBz, naphthalene-linked ammonium bromides Nap and PbBr2 Pb (the molar ratio;C3 : CBz : Pb and C3 : Nap : Pb= 4 : 2: 3) were dissolved .
