Extraction of natural dye was done using different solvents as ethanol, acetone and isopropanol. Optical properties of natural dye were studied by UV-vis spectroscopic measurement. Characterization results showed high absorbance values 0.3764, 0.2251 and 0.42 at 615 nm, 510 nm and 525 nm for ethanol, acetone and isopropanol. The optimum energy band gap values in this study were 2 eV, 2.42 eV and 2.35 eV at 615 nm, 510 nm and 525 nm for ethanol, acetone and isopropanol solvents at room temperature (25 oC). The optimum values of absorption coefficient of Strawberry dye with ethanol, acetone and isopropanol solvents were 1.76 km-1, 2.12 km-1 and 2.06 km-1 at room temperature (25 oC). In this study, two methods were used to calculate the band gap energy values and they were nearly equal."}]}, "item_1583103108160": {"attribute_name": "Keywords", "attribute_value_mlt": [{"interim": "Strawberry dye"}, {"interim": "photosensitizer"}, {"interim": "absorbance and band gap energy"}]}, "item_1583103120197": {"attribute_name": "Files", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_access", "date": [{"dateType": "Available", "dateValue": "2020-10-01"}], "displaytype": "preview", "download_preview_message": "", "file_order": 0, "filename": "Optical Properties of Natural Dye from Strawberry Fruits as Photosensitizer for Dye-Sensitized Solar Cells Application.pdf", "filesize": [{"value": "342 Kb"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_0", "mimetype": "application/pdf", "size": 342000.0, "url": {"url": "https://meral.edu.mm/record/5571/files/Optical Properties of Natural Dye from Strawberry Fruits as Photosensitizer for Dye-Sensitized Solar Cells Application.pdf"}, "version_id": "eff31dc2-6d6e-46dc-aa80-77dcaad48eb4"}]}, "item_1583103131163": {"attribute_name": "Journal articles", "attribute_value_mlt": [{"subitem_issue": "3", "subitem_journal_title": "University of Mandalay, Research Journal", "subitem_pages": "178 - 186", "subitem_volume": "11"}]}, "item_1583105942107": {"attribute_name": "Authors", "attribute_value_mlt": [{"subitem_authors": [{"subitem_authors_fullname": "Nan Kyi Kyi Thein"}, {"subitem_authors_fullname": "Aung Htet"}, {"subitem_authors_fullname": "Thwe Thwe Aye"}]}]}, "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": "2020-05-01"}, "item_title": "Optical Properties of Natural Dye from Strawberry Fruits as Photosensitizer for Dye-Sensitized Solar Cells Application", "item_type_id": "21", "owner": "23", "path": ["1582963739756", "1582967025340"], "permalink_uri": "http://hdl.handle.net/20.500.12678/0000005571", "pubdate": {"attribute_name": "Deposited date", "attribute_value": "2020-10-01"}, "publish_date": "2020-10-01", "publish_status": "0", "recid": "5571", "relation": {}, "relation_version_is_last": true, "title": ["Optical Properties of Natural Dye from Strawberry Fruits as Photosensitizer for Dye-Sensitized Solar Cells Application"], "weko_shared_id": -1}
