Spectroscopic analyses reveal that the emissions are due to Forster resonance energy transfer (FRET) between the energy donor and acceptor nanoparticles. The energy transfer efficiencies are high, reaching over 90% in the film state due to the close packing of NDs while in their film state. Various molar ratios produced different colors in both liquid dispersions and in the solid state. These CTONDs demonstrate over 60% color conversion efficiency (CCE) when applied as color conversion layers (CCLs) in light\u2010emitting devices, maintaining photostability for over four months under ambient conditions. Additionally, their aqueous processability and multicolor tunability make them attractive for environmentally friendly display technologies, flexible optoelectronics, and anti\u2010counterfeiting applications such as security inks. This work offers a scalable and sustainable approach to fabricating tunable, solution\u2010processed fluorescent organic nanomaterials and underscores their promise as a versatile platform for next\u2010generation photonic and optoelectronic applications.<\/jats:p>","DOI":"10.1002\/smll.202505043","type":"journal-article","created":{"date-parts":[[2025,7,11]],"date-time":"2025-07-11T06:59:21Z","timestamp":1752217161000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Color\u2010Tunable Organic Nano\u2010Dots: Synthesis and Applications in Color Conversion and Security Inks"],"prefix":"10.1002","volume":"21","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3958-0319","authenticated-orcid":false,"given":"Yeasin","family":"Khan","sequence":"first","affiliation":[{"name":"Department of Chemistry Kyung Hee University  26 Kyungheedaero, Dongdaemun\u2010gu Seoul 02447 Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rasheeda","family":"Ansari","sequence":"additional","affiliation":[{"name":"Organic Optoelectronic Device Lab.
