These PQD analogs open new possibilities for optoelectronic devices. For commercial applications in lighting and backlight displays, stability of PQDs requires further improvement to prevent their degradation by temperature, oxygen, moisture, and light. Oxygen and moisture‐facilitated ion migration may easily etch unstable PQDs. Easy ion migration may result in crystal growth, which lowers PLQY of PQDs. Surface coating and treatment are important procedures for overcoming such factors. In this study, new types of PQDs and a strategy of improving their stabilities are introduced. Finally, this paper discusses future applications of PQDs in light‐emitting diodes.</jats:p>"}]}],"creator":[{"@id":"https://cir.nii.ac.jp/crid/1380579816828351106","@type":"Researcher","foaf:name":[{"@value":"Hung‐Chia Wang"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry National Taiwan University  Taipei 106 Taiwan"}]},{"@id":"https://cir.nii.ac.jp/crid/1381699993637589635","@type":"Researcher","foaf:name":[{"@value":"Zhen Bao"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry National Taiwan University  Taipei 106 Taiwan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380579816828351105","@type":"Researcher","foaf:name":[{"@value":"Hsin‐Yu Tsai"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry National Taiwan University  Taipei 106 Taiwan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380579816828351104","@type":"Researcher","foaf:name":[{"@value":"An‐Cih Tang"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry National Taiwan University  Taipei 106 Taiwan"}]},{"@id":"https://cir.nii.ac.jp/crid/1380579816828351107","@type":"Researcher","foaf:name":[{"@value":"Ru‐Shi Liu"}],"jpcoar:affiliationName":[{"@value":"Department of Chemistry National Taiwan University  Taipei 106 Taiwan"},{"@value":"Department of Mechanical Engineering and Graduate Institute of Manufacturing Technology National Taipei University of Technology  Taipei 106 Taiwan"}]}],"publication":{"publicationIdentifier":[{"@type":"PISSN","@value":"16136810"},{"@type":"EISSN","@value":"16136829"}],"prism:publicationName":[{"@value":"Small"}],"dc:publisher":[{"@value":"Wiley"}],"prism:publicationDate":"2017-11-30","prism:volume":"14","prism:number":"1","prism:startingPage":"1702433"},"reviewed":"false","dc:rights":["http://onlinelibrary.wiley.com/termsAndConditions#vor"],"url":[{"@id":"https://api.wiley.com/onlinelibrary/tdm/v1/articles/10.1002%2Fsmll.201702433"},{"@id":"https://onlinelibrary.wiley.com/doi/pdf/10.1002/smll.201702433"}],"createdAt":"2017-11-30","modifiedAt":"2023-09-30","relatedProduct":[{"@id":"https://cir.nii.ac.jp/crid/1360021390555619840","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"In-situ TiO2-Coated CsPbBr3 quantum dots with enhanced stability, photoluminescence quantum yields, and charge transport properties"}]},{"@id":"https://cir.nii.ac.jp/crid/1360572092698243712","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"High luminescence and external quantum efficiency in perovskite quantum-dots light-emitting diodes featuring bilateral affinity to silver and short alkyl ligands"}]},{"@id":"https://cir.nii.ac.jp/crid/2050588892112988288","@type":"Article","resourceType":"学術雑誌論文(journal article)","relationType":["isReferencedBy"],"jpcoar:relatedTitle":[{"@value":"Development of precisely controlled structures containing main group elements for preparing superatoms"}]}],"dataSourceIdentifier":[{"@type":"CROSSREF","@value":"10.1002/smll.201702433"},{"@type":"CROSSREF","@value":"10.1016/j.ceramint.2022.07.196_references_DOI_XMqgVltRJ0AAJhdFBlxRaNYV2BZ"},{"@type":"CROSSREF","@value":"10.1016/j.cej.2021.128866_references_DOI_XMqgVltRJ0AAJhdFBlxRaNYV2BZ"},{"@type":"CROSSREF","@value":"10.1246/cl.220291_references_DOI_XMqgVltRJ0AAJhdFBlxRaNYV2BZ"}]}
