Luminescent white lighting is often impure, inefficient, expensive, and detrimentally emits\u00a0as a point source, meaning the light is emitted from a focused point. A luminescent light diffuser offers the potential to create a spatially broad lighting fixture. We developed a luminescent light diffuser consisting of three commercially available luminescent dye species (rhodamine 6G, fluorescein, 7\u2010diethylamino\u20104\u2010methylcoumarin) dispersed within a polymer matrix (polyvinyl alcohol), or commercial paint, and coated on a planar waveguide. A Light\u2010emitting diode (LED) (385\u2009nm) is directed into the waveguide which excites the luminescent species, coating the panel, creating a device that emits spatially broad pure white light. As the emission depends on escape cone emission from the waveguide, the device\u2019s emission was found to depend highly on the coating film quality and components. We present two systems: a small 40\u2009mm\u2009\u00d7\u200940\u2009mm prototype, made using standard water\u2010soluble polymer (polyvinyl alcohol), to study the underlying operational principles, and a 100\u2009mm \n 100\u2009mm device with optimized efficiency fabricated with a clear commercial paint. By doping the polymer matrix with scattering silica microparticles we achieved a maximum photon outcoupling efficiency of 78%, whilst maintaining colour purity with an increased device size of more than 300 times (compared with the input LED). This work shows that it is possible to construct an inexpensive and spatially broad lighting source, whilst maintaining colour purity at a low cost.<\/jats:p>","DOI":"10.1002\/bio.4416","type":"journal-article","created":{"date-parts":[[2022,11,26]],"date-time":"2022-11-26T09:47:56Z","timestamp":1669456076000},"page":"47-55","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Luminescent light diffuser for diffuse lighting applications"],"prefix":"10.1002","volume":"38","author":[{"given":"Amy","family":"Witzmann","sequence":"first","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Calum K.","family":"Gordon","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jesse","family":"Howarth","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sophie","family":"Unsworth","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aur\u00e9lien","family":"Rossi","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jake","family":"Hardy","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael B.","family":"Price","sequence":"additional","affiliation":[{"name":"School of Chemical and Physical Sciences, The MacDiarmid Institute for Advanced Materials and Nanotechnology, The Dodd\u2212Walls Centre for Photonic and Quantum Technologies Victoria University of Wellington  Wellington New Zealand"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2535-8968","authenticated-orcid":false,"given":"Nathaniel J.
