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.

Abstract In recent years, there is a growing interest in developing ultralong organic room‐temperature phosphorescence (ORTP) with lifetimes the range of seconds. As one important three primary colors, blue ORTP an indispensable core component RTP regulation and application, however, large Stokes shift characteristics pose certain challenges ORTP. Here, new family phosphors are synthesized realized through crystal assembly water phase. Remarkably, compared to materials obtained phases, enabled long‐lived up 2.3 s quantum yield reached as high 29.27%. addition efficient green form, such dark possessed thermal stability flexible tunability. Moreover, superiority selected components demonstrated by comparing them polymer proposed show great potential programmable information encryption/anti‐counterfeiting.

Sustainable photoactivated room temperature phosphorescent materials exhibit great potential but are difficult to obtain. Here, we develop by covalently attaching lignin polylactic acid, where and acid the chromophore matrix, respectively. Initially phosphorescence of is quenched residual O2. However, switched on when oxygen consumed triplet excitons under continuous UV light irradiation. As such, lifetime increases from 3.0 ms 221.1 after 20 s activation. Interestingly, again being kept an atmosphere air for 2 h in absence irradiation due diffusion into materials. Using these properties, as-developed material successfully used as a smart anti-counterfeiting logo medicine bottle information recording. Convenient sustainable (RTP) wide ranging applications Here authors RTP acid.

Abstract The efficient utilization of clean and safe sunlight as an excitation source for room‐temperature phosphorescent (RTP) materials is crucial practical applications in solar energy. Herein, sunlight‐activated RTP nitrogen‐doped carbon dots @ alumina (N‐CDs@Al 2 O 3 ) composites with long lifetime exceptional stability are designed fabricated using situ preparation strategy. N‐CDs@Al display bright yellow (more than 18 s to the naked eye) when activated by sunlight. results indicate that introduction nitrogen into CDs not only promotes effective filling triplet excitons but also facilitates red‐shift absorption spectrum CDs. high rigidity structure Al stable strong covalent bonds effectively protect excitons. Additionally, numerous oxygen vacancy defects formed under appropriate calcination conditions store release Finally, application multi‐color 3D artworks, defense markings, emergency signs demonstrated. This work provides design principles feasible strategies development new materials.
