Novel doped polystyrene (PS)/porous silicon (PSi) heterojunction photodetector prepared by solution cast and electrochemical techniques is proposed here. The structural and optical properties of polystyrene film and porous silicon surface were investigated using X-ray diffraction (XRD), scanning electron microscope, Fourier transformed infrared (FT...

In this paper, methyl-orange-doped polystyrene (PS) microspheres covered with gold and silver nanoparticles (NPs) have been synthesized. The optical and structural properties of the porous polystyrene films before and after incorporation of Au and Ag nanoparticles were investigated using X-ray diffraction (XRD), scanning electron microscope (SEM),...

... Electrochemical etching, where silicon as an anode and an electrolyte is etched with an external power supply and light assistance [3], is an efficient and simple way to prepare porous structures, and so it has been extensively used in many areas of research and in numerous applications. Porous silicon nanocrystalline PSi has a wide band gap as compared with bulk crystalline silicon and it is the most favorable layer in the different utilizations consequent to the unique properties such as surface area relative to volume, porosity, electrical, and optical properties [4]. The pore diameter and wall thickness of the porous silicon can be manipulated via adjusting the electrochemical etching parameters. ...
... On the other hand, collection of these nanoplatelets leads to the production of Bi 2 O 3 nanoflowers [16]. The EDX was very important tool to estimate the composition of the product [17]. Figure 4 shows the EDX spectra of BO and BOMF samples. ...
