Abstract Producing mechanic robust and sustainable room temperature phosphorescent (RTP) films in a convenient manner is fundamental requirement but remains challenging. Here, an efficient “top‐down” method for processing natural wood into RTP developed. Specifically, partially delignified to increase its processability the first step. After that, treated converted W‐film with tensile strength of 273.6 MPa via mechanical pressing. The lignin units are well confined by cellulose W‐film, triggering emission lifetime ≈241.9 ms. Additionally, exhibits good energy transfer properties Rhodamine B (RhB). Therefore, series multifunctional afterglow 2D 3D materials constructed using as building block. This research expected result preparation films.

Producing room temperature phosphorescent materials from natural sources is essential for sustainability. However, either toxic chemical reagents or complicated processing still required to produce such derived resources. Here, we sustainable phosphorescence (RTP) wood and sugar. Specifically, sugar introduced into a matrix, which confines the lignin in matrix situ. As result, treated (sucrose [S-wood]) exhibited RTP emissions with lifetime of ∼284.4 ms. Life cycle carbon analysis indicates that ∼8.1–11.2 kg CO2 produced during preparation S-wood, lower than other similar materials. Moreover, S-wood could be naturally degraded soil over 40 days. demonstration practical potential, used visual decorations anti-counterfeiting applications.

Abstract Stimuli‐responsive materials exhibiting exceptional room temperature phosphorescence (RTP) hold promise for emerging technologies. However, constructing such systems in a sustainable, scalable, and processable manner remains challenging. This work reports bio‐inspired strategy to develop RTP nanofiber using bacterial cellulose (BC) via bio‐fermentation. The green fabrication process, high biocompatibility, non‐toxicity, abundant hydroxyl groups make BC an ideal biopolymer durable stimuli‐responsive materials. Remarkable performance is observed with long lifetimes of up 1636.79 ms at temperature. Moreover, moisture can repeatedly quench activate dynamic tunable fashion by disrupting rigidity permeability. With capabilities repeatable moisture‐sensitive phosphorescence, these are highly suitable applications as anti‐counterfeiting information encryption. pioneering bio‐derived approach provides reliable sustainable blueprint dynamic, beyond synthetic polymers.
