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