Effect of dopant of aluminum on the structural and optical properties of NiTsPc thin films

Abstract

The (NiTsPc) thin films operating by vacuum evaporation technique are high recital and good desirable for number of applications, were dumped on glass substrates at room temperature with (200±20nm) thickness and doped with Al at different percentage (0.01,0.03) besides annealing the sample with 200˚C for 1 hours . The stimuluses of aluminum dopant percentage on characterization of the dropped (Ni Ts Pc) thin films were studied through X-ray diffraction in addition from the attained results, were all the films have polycrystalline in nature, as well the fallouts of XRD aimed at film illustrations polycrystalline, depending on the Al ratio doping, the results, SEM exposed the surface is regularly homogeneous. Utilizing first-ideologies calculations, we demonstration that appropriate band gaps and optical properties adjacent to that of direct energy gap intended for wholly samples.

Effect of ratio gold nanoparticles on the properties and efficiency photovoltaic of thin films of amorphous tungsten trioxide

“…Metal nanoparticles' color and optical characteristics are caused by surface plasma resonance (SPR), a collective longitudinal excitation of conduction electrons on the nanoparticles' surface [7]. The primary goal of this study is to fabricated (n-WO 3 /p-Si) heterojunction with doped tungsten oxide films in various concentrations of gold nanoparticles (0, 0.04, 0.08 M) by using the spray pyrolysis technique, which is one of the processes used to produce and prepare thin films of tungsten trioxide [8][9][10][11][12][13][14][15], as well as to examine the structural, optical, and surface characteristics of the prepared samples.…”
