“…The lattice strain was calculated by using the Williamson-Hall equation with the parameters from the XRD observation. 24) The equation indicated lattice strain inversely proportional with crystallite size. Peak values of Urbach energy variation (where the highest peak in the energy spectrum have been obtain in wavelength of 750 nm) correspond to absolute value of the lattice strain (Fig.…”

A 250 nm thick pure tin film was deposited on quartz substrates by vacuum evaporation of 99.9% pure tin metal. The films were heated in a two-step annealing sequence for 3 h at 200 and 3 h at 400°C with an electric furnace to decrease their surface roughness. This process transformed the films into tin(II) oxide. Subsequently, the films were annealed at five temperatures for 3 h each: 600, 700, 800, 900 and 1000°C. The crystal structure of the film on the quartz substrate was completely transformed into SnO 2 at 600°C. With the increase of annealing temperature to 1000°C, the size of the lattices appeared to decrease on the thin film. In addition, the annealing process led to the formation of pores on the surface, but the number of pores and the lattices volume decreased with increased annealing temperature. The optical properties of the thin film were characterized by the use of visible spectrophotometry which showed a high refractive index at around 2.082.27. Interestingly, the SnO 2 thin film with the highest refractive index at 2.27, which was obtained at 1000°C, exhibited the lowest Urbach energy. Therefore, the SnO 2 thin film has a high potential for optical applications, especially in dielectric waveguides and solar cells.

The need for affordable, clean, efficient, and sustainable solar cells informed this study. Metal oxide TiO2/NiO heterojunction solar cells were fabricated using the spray pyrolysis technique. The optoelectronic properties of the heterojunction were determined. The fabricated solar cells exhibit a short-circuit current of 16.8 mA, open-circuit voltage of 350 mV, fill factor of 0.39, and conversion efficiency of 2.30% under 100 mW/cm2 illumination. This study will help advance the course for the development of low-cost, environmentally friendly, and sustainable solar cell materials from metal oxides.

“…Optical waveguides of oxide material in this case Tin Oxide (SnO2) implanted in the channel polymer channel in this case akrylic. SnO2 one of the semiconductor metal oxide films has attracted considerable interest because of its electrical conductivity and good optical properties [11] with an energy gap gap that is greater than 3.6 eV [12] and is transparent [13]. Several methods that have been used to make wave guides with SnO2 nanoparticles are CO2 laser cutting methods [14], chemical spray pyrolysis [15][16], chemical bath deposition [17], chemical vapor deposition [18] and spin coating [19].…”

Engraving of polymer materials using cutting laser is a popular process in some manufacturing industries. This research presents the manufacture of waveguides channels on polymethyl methacrylate (PMMA) substrate using CO2 cutting laser process. The CO2 laser engraving machine has cost effective and takes less time than other tools in waveguide channels fabrication. In this work, we integrated optical components such as waveguide for directional coupler application using tin oxide which is embedded and interconnected in PMMA substrate. In the fabrication channels waveguide with grafir on PMMA subtrate with 4.2 mW laser power and speed 10 mm/s and then repeated two times. The waveguide channels profile is made with curvature angle variation for branching (17 o , 36 o and 54 o). Characterization of waveguide directional coupler is done by measuring the intensity of the output at each port cross-section of the waveguide directional coupler when given an input beam He-Ne laser (632.8 nm). The results directional coupler fabrication using CO2 laser cutting machine can achieve optimum with a very small loss of 3.3% when compared to the straight waveguide coupler channel. Thus, CO2 laser cutting processing as an optical waveguide fabrication can produce channels on PMMA material more effectively.
