Study on Photo-physical Properties of News Synthesized Olygophenylene Derivatives

UV-visible (UV-vis), steady-state, and time-resolved photoluminescence spectroscopies are used to investigate the photophysical properties of freshly synthesised oligophenylene derivatives in this chapter. Knoevenagel condensation of produced oligo[4-(methoxyphenyl) acetonitrile] (OMPA) with various chemical groups…

Analysis of Spectral Reflectance of Layers Formed by Anodic Etching of Silicon

In several applications in optoelectronics and photovoltaics, porous silicon structures are employed to reduce spectrum reflectance. We were able to make porous silicon structures by anodizing p-type silicon substrates. Various etching conditions, such…

The Influence of Bio Natural Dye on the Optical Properties of Liquid Polyvinyl Alcohol

The use of bio liquid electrolytes in solar cells enhances cell performance, minimises electrostatic charge on the surface, and reduces the possibility of solid electrolyte leakage. In addition to yellow dye produced from…

Studies of Optical and Phonon Properties of Wurtzite Gallium Nitride: First-principle Calculations

Using the plane-wave pseudopotential approach inside density functional theory, we investigated the optical properties of wurtzite (WZ) GaN semiconductor such as refractive index n(), absorption coefficient (), and dielectric constant (DFT). The optical…
