Researchers from University of Baghdad Report Recent Findings in Nanoparticles (Manufacturing and Investigation of Barium Oxide Thin Films for Photodetector Applications)

2024 AUG 07 (NewsRx) -- By a News Reporter-Staff News Editor at Middle East Daily -- Investigators publish new report on Nanotechnology - Nanoparticles. According

Article Description

Barium oxide was made in this work using an easy and affordable chemical technique. FTIR, AFM UV-visible, and X-ray diffraction (XRD) are used to describe the produced samples. The tetragonal phase of BaO nanoparticles with an average crystallite size of 46.5 nm was verified by X-ray diffraction experiments. The particle size was determined to be between 40 and 201 nm using the AFM micrograph. It was discovered that the BaO nanoparticles optical band gap was 4.6 eV. The sample's presence of Ba-O vibration was detected by FTIR spectra. Regarding the Operation of (Ag/BaO/Si/Ag), photodetector studied the effect of changing the molar concentration (M) for barium oxide (1M, 0.5M and 0.25M). The properties of the applied photodetector were studied, by the responsivity (Rλ) of all photodetectors. The higher responsivity was about 0.18A/W, the Specific Detectivity (D*) was 2.5 × 10 and Quantum Efficiency (η) 49% at 0.5M for wavelength 450nm.
