A novel self-luminous wood coating with carbon dots (CDs)\/titanium dioxide (TiO2) nanomaterial coated SrAl2O4: Eu2+, Dy3+ (CDs\/TiO2@SAO) composite was prepared for the long-term degradation of formaldehyde through a simple sol-gel method. The microstructure, chemical composition, ultraviolet-visible (UV-vis) spectra, and long-lasting fluorescence of the CDs\/TiO2@SAO photocatalyst were analyzed to illustrate the mechanism for degrading formaldehyde. The obtained CDs with a particle size of ~2\u20137 nm have a good graphite structure and presented good absorption in visible light. In addition, owing to the synergistic effect of the CDs\/TiO2 nanomaterial coating layer and the long-afterglow luminescence of the SAO phosphor, the CDs\/TiO2@SAO composite can absorb a part of the visible light for photocatalytic degradation and store luminous energy efficiently at daytime so as to give out visible luminescence continuously for a few hours in the darkness. Furthermore, the functional wood coatings with CDs\/TiO2@SAO composite presented continuous and efficient photocatalytic activity in the presence and absence of light exposure. The current research could provide a new strategy for designing an efficient photocatalyst for degrading formaldehyde pollution in the daytime with a visible light supply and in an indoor dark environment without an external light source.<\/jats:p>","DOI":"10.3390\/polym15092077","type":"journal-article","created":{"date-parts":[[2023,4,28]],"date-time":"2023-04-28T01:33:40Z","timestamp":1682645620000},"page":"2077","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Self-Luminous Wood Coatings with Carbon Dots\/TiO2 Grafted Afterglow SrAl2O4: Eu, Dy Core-Shell Phosphors for Long-Lasting Formaldehyde Removal"],"prefix":"10.3390","volume":"15","author":[{"given":"Longfei","family":"Zhang","sequence":"first","affiliation":[{"name":"Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China"},{"name":"Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, Nanjing Forestry University, Nanjing 210037, China"},{"name":"National Forestry and Grassland Administration Key Laboratory of Plant Fiber Functional Materials, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Wang","sequence":"additional","affiliation":[{"name":"Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Limin","family":"Peng","sequence":"additional","affiliation":[{"name":"Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2552-0577","authenticated-orcid":false,"given":"Zhilin","family":"Chen","sequence":"additional","affiliation":[{"name":"Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shaoyi","family":"Lyu","sequence":"additional","affiliation":[{"name":"Research Institute of Wood Industry, Chinese Academy of Forestry, Beijing 100091, China"},{"name":"Co-Innovation Center of Efficient Processing and Utilization of Forest Resources, Nanjing Forestry University, Nanjing 210037, China"},{"name":"National Forestry and Grassland Administration Key Laboratory of Plant Fiber Functional Materials, Fuzhou 350002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5666-9390","authenticated-orcid":false,"given":"Siqun","family":"Wang","sequence":"additional","affiliation":[{"name":"Center for Renewable Carbon, University of Tennessee, Knoxville, TN 37996, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"102","DOI":"10.1016\/j.jhazmat.2017.05.013","article-title":"Adsorption of VOCs onto engineered carbon materials: A review","volume":"338","author":"Zhang","year":"2017","journal-title":"J.
