The annealed ZnO powders were studied by Scanning Electron Microscope (SEM), X-ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), and UV-Vis Spectroscopy to get the results of the structural and optical properties. The average crystallite size of ZnO increased with increasing annealing temperatures. The full width at half maximum (FWHM) of ZnO particle decreases with increasing annealing temperatures assuming an increase in particle growth. The grain sizes were also studied to be increased with an increase in annealing temperatures. The SEM images illustrated that the shape of ZnO was an irregular spherical shape and agglomerated. The variations in size and shape of ZnO are due to the difference in precursor and annealing temperature. The various functional groups for synthesized ZnO were detected by FT-IR spectroscopy analysis. The FT-IR peaks exactly to the vibrational phonons of ZnO also verify the successful making of ZnO particles. The optical properties of the samples were investigated by measuring the UV-Visible Spectroscopy. The data from UV-vis examined the ZnO samples be influenced by different annealing temperatures."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "ZnO"}, {"interim": "XRD"}, {"interim": "SEM"}, {"interim": "FTIR"}, {"interim": "UV-vis"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2024-05-03"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Amy Aung (267 to 274).pdf", "filesize": [{"value": "473 KB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 473000.0, "url": {"url": "https://meral.edu.mm/record/9438/files/Amy Aung (267 to 274).pdf"}, "version_id": "e0e8c841-8a7b-488f-9a4e-55fb85df893f"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "2022", "subitem_journal_title": "University of Yangon Research Journal 2022", "subitem_pages": "267-274", "subitem_volume": "Vol. 11, No.2"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Amy Aung"}, {"subitem_authors_fullname": "May Kalayar Kyaing"}, {"subitem_authors_fullname": "Ohn Mar Swe"}, {"subitem_authors_fullname": "Zin Mar Win"}]}]}, "item_1583108359239": {"attribute_name": "Upload type", "attribute_value_mlt": [{"interim": "Publication"}]}, "item_1583108428133": {"attribute_name": "Publication type", "attribute_value_mlt": [{"interim": "Journal article"}]}, "item_1583159729339": {"attribute_name": "Publication date", "attribute_value": "2022-12-31"}, "item_title": "Investigation of Structural and Optical Properties of Zinc Oxide (ZnO) Powder by Co-Precipitation Method", "item_type_id": "21", "owner": "235", "path": ["1582967549708"], "permalink_uri": "https://meral.edu.mm/records/9438", "pubdate": {"attribute_name": "Deposit date", "attribute_value": "2024-05-03"}, "publish_date": "2024-05-03", "publish_status": "0", "recid": "9438", "relation": {}, "relation_version_is_last": true, "title": ["Investigation of Structural and Optical Properties of Zinc Oxide (ZnO) Powder by Co-Precipitation Method"], "weko_shared_id": -1}
