Publication Metadata only Indium-based quantum dots trapped in solid-state matrices: a one-pot synthesis, thermoresponsive properties, and enhanced micropollutant removal(Royal Society of Chemistry, 2024) Ük, Nida; Aykut, Sümeyye; Nar, Ilgın; Ünlü, Caner; Jahangiri, Hadi; Koç University Surface Science and Technology Center (KUYTAM) / Koç Üniversitesi Yüzey Teknolojileri Araştırmaları Merkezi (KUYTAM); ;Indium-based quantum dots (QDs), such as copper indium disulfide and zinc copper indium sulfide, have been the center of research for decades due to their low toxicity and unique photophysical properties. In contrast, versatile indium-based materials like In2S3 and ZnIn2S4 have been rarely studied in their QD form because of the challenges in their synthesis and used in solid-state material based applications because of their colloidal nature. In this study, a one-pot single-step method to synthesize In2S3, ZnIn2S4, and Cu-doped ZnIn2S4 QDs trapped in insoluble solid-state oleic acid matrices was developed. The QDs in solid-state matrices exhibited bright orange colored fluorescence with controllable emission properties achieved by altering the chemical composition. Among these QDs, the ZnIn2S4 QDs displayed thermo-responsive properties. As the temperature increased, the fluorescence intensity of ZnIn2S4 QDs decreased. In addition, all QDs demonstrated high removal efficiency for micropollutants in the aqueous medium, especially against cationic organic dyes. This study represents one of the first attempts at the direct development of QDs trapped in insoluble solid-state matrices. The QDs in solid-state matrices hold promise for applications in thermal sensors and studies related to the micropollutant removal. © 2024 The Royal Society of Chemistry.Publication Restricted InP quantum dot based light-emitting and neuro-stimulating optoelectronic devices(Koç University, 2019) Karatüm, Onuralp; Nizamoğlu, Sedat; 0000-0003-0394-5790; Koç University Graduate School of Sciences and Engineering; Electrical and Electronics Engineering; 130295Publication Restricted Investigation of phototherapeutic effect of photosensitizer coated quantum dot nanoparticles on trichophyton rubrum(Koç University, 2022) Öztürk, Sevgi; Doğan, Özlem; 0000-0002-6505-4582; Koç University Graduate School of Health Sciences; Medical Microbiology; 170418Publication Restricted Spectroscopic investigation of CdS quantum dots and Fe2+: ZnSe(Koç University, 2007) Erdamar, Ahmet Koray; Sennaroğlu, Alphan; 0000-0003-4391-0189; Koç University Graduate School of Sciences and Engineering; Physics; 23851
