Abstract

Optical switch represents good technology components used in many application especially in communication. Optical switch is different from conventional one having many advantageous. Single mode fiber optics is used as a waveguide for propagating the power of Laser Source and detected by power meter. The design is started by connecting single mode fiber optics to the source and detector. The voltage source is measured  corresponding to power meter detector. The result shows that the lowest output power is detected from the paraffin of -39,28 dBm and fiber the output power is -12,67 dBm. The maximum input voltage is 3200 Volt and output voltage is 1061 Volt for optical fiber and the lowest electric field obtained is 223,2 x 10−11A/m2. The current density is 223,2 x 10−11 A/m2  for paraffin with 500 μm in diameter. The output voltage for paraffin 1032 Volt, the electric field of 412,8 x 104 V/m and current densityis 412,8 x 10−11 A with 250 μm in diameter.

Abstract

TiO2 nanoparticles have been grown successfully by electrodeposition method on the surface of Fluorine Tin Oxide (FTO) substrate. The growth of TiO2 nanoparticles was done by using voltage of 2 Volt, 6 Volt, 10 Volt, 14 Volt and 18 Volt. This TiO2 was also demonstrated with two different temperature 37 oC and 50 oC. The samples were characterized by UV-Vis spectroscopy, X-ray Diffraction, Scanning Electron Microscope (SEM) and Energy Dispersion X-ray (EDX). The results of UV-Vis showed that TiO2 nanoparticles have the highest absorption at 18 Voltage. The result of XRD at 18 Volt showed that TiO2 has 5 peaks at 2θ: 25,497o, 38,176o, 38,176o, 51,887o, 54,911 o, and 62,093 o, with their crystal plane (1 1 1), (2 1 1 ), (2 2 2), (3 2 0), (4 0 0). The results of SEM showed that nanoparticles form is nearly spherical at a magnification of 35000 times. The results of EDX of the review indicate that Ti atoms have a percentage atomic of 17.66% and O of 70,39%.

Abstract

Silver nanoparticles have been successfully grown on solid substrate. The growth of the particles used wet chemical  method which consisted of two steps, seeding and growing steps. The silver nanoparticle growth was carried out by two variations which were surfactant’s concentration and ascorbic acid’s volume.  The UV-Vis spectrum profile of the samples described that the  growth of silver nanoparticles of spherical shape was dominated on the ITO, represented as a sharp single peak of the absorption spectra. Its characterization measured by XRD showed that silver nanoparticles had grown on the substrate with crystal orientation (1 1 1) and (2 0 0). The FESEM images depicted that the shape of silver nanoparticles was a spherical shape with their uniform diameter size of 300-650 nm.
