This research was conducted to analyze the Mg doping concentration effect on the structure, morphology, and optical properties of ZnO thin film prepared using the sol gel spin coating method. The Mg concentration was varied in the mole fraction of 1%, 3%,... see more

Dosimeter is one of the apparatus needed by radiation workers. From a dosimeter, radiation workers can control the absorbed dose. This research aims to investigate the properties characteristics of chitosan film for dosimeter usage. Thin-film chitosan pol... see more

Monoclinic tungsten oxide (WO3) nanoplates were synthesized via a two-step simple process: acid precipitation at room temperature to prepare WO3.H2O nanoplates and annealing at high temperature (400 and 500 oC) in ambient air to obtain WO3 nanoplates. The... see more

A thin layer of Barium Strontium Titanate Ba0.15Sr0.85TiO3 (BST) was developed on a glass substrate using a sol-gel method with annealing temperatures and spin coating process at 3500 rpm for 30 seconds. The annealing temperature varied from 600oC, 650oC,... see more

By using spin-coating technique, a low bandgap conjugated polymer, poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopen-ta[2,1-b;3,4-b']dithiophene)-alt-4,7-(2,1,3-benzothiadiazole)] (PCPDTBT)  and its composite thin films have been prepared. The optical abs... see more

ZnTe thin films were prepared by Stacking of elemental (Zn and Te) layers (SEL) followed by inert gas annealing. The optical parameters were calculated from the transmission spectra. The bandgap of the annealed samples was found between 1.95 eV ... see more

The electronic and optical properties of a-Al2O3 after induced by 3-keV Ar+ sputtering  have been studied quantitatively by use of reflection electron energy loss spectroscopy (REELS) spectra. The band gap values of a-Al2O3 was determined from the on... see more

This paper demonstrates the synthesis of NixCd1-xS (x=0.8,0.6,0.4,0.2) nanoparticles by microwave-assisted chemical precipitation method. The prepared samples were characterized by XRD, EDAX, SEM, UV-VIS, and PL spectroscopy. The energy-dispersive x-ray a... see more

AbstrakTelah dilakukan studi eksperimen untuk meneliti pengaruh penggunaan sumber metalorganik baru yakni trimethylgallium (TMGa) dan trisdimethylaminoarsenic (TDMAAs) yang dikombinasi dengan variasi temperatur penumbuhan terhadap sifat optik film tipis G... see more
