The weakly\u2010twisted CNCs, hierarchically organized through evaporation\u2010induced self\u2010assembly, act as chiral scaffolds enforcing the supramolecular chirality. The ensuing composite CNC films display dye\u2010specific photoluminescence with maximum negative luminescence dissymmetry () values of \u22120.15, \u22120.16, and \u22120.11 for blue, green, and red emissive films, respectively, indicative of preferential right\u2010handed emission. Morphological evaluation via scanning electron microscopy (SEM) reveals well\u2010defined Bouligand arches, and studies by polarized optical microscopy (POM) fingerprint textures, each confirming the preservation of chiral nematic ordering across all emissive films. Notably, by integration of all three fluorescent dyes within the CNC matrix, near\u2010white CPL was achieved by color mixing, as corroborated by CIE 1931 chromaticity analysis with  values ranging from 0.05 to 0.10 over the visible spectral region, with 90% permanence of the fluorescence over a 12\u2010h irradiation period. This approach establishes the basic framework for generating mechanically and thermally robust CPL\u2010active, principally bio\u2010renewable chiral CNC materials and optical elements for advanced displays, optoelectronic devices, and chiroptical sensing platforms.<\/jats:p>","DOI":"10.1002\/chem.71627","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T07:06:50Z","timestamp":1788246410000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Near\u2010White Circularly Polarized Luminescence by Color Mixing Utilizing Surface\u2010Fluorophore\u2010Modified Cellulose Nanocrystals in Composite Films"],"prefix":"10.1002","volume":"32","author":[{"given":"Asmita","family":"Shah","sequence":"first","affiliation":[{"name":"Advanced Materials and Liquid Crystal Institute (AMLCI) Kent State University  Kent Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-7159-1336","authenticated-orcid":false,"given":"Timothy G.","family":"Lerch","sequence":"additional","affiliation":[{"name":"Department of Chemistry Millersville University of Pennsylvania  Millersville Pennsylvania USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0009-8321-0663","authenticated-orcid":false,"given":"Gourab","family":"Acharjee","sequence":"additional","affiliation":[{"name":"Advanced Materials and Liquid Crystal Institute (AMLCI) Kent State University  Kent Ohio USA"},{"name":"Department of Chemistry &amp; Biochemistry Kent State University  Kent Ohio USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8457-1166","authenticated-orcid":false,"given":"Grace A.
