Abstract

Fabricating sustainable room‑temperature phosphorescent (RTP) films without relying on intrinsic chromophores constitutes a fundamental objective, yet it remains an enduring challenge. Here, we present an efficient “top‑down” strategy that directly converts natural bamboo into RTP films. Furthermore, delignification was performed on natural bamboo to extract lignin constituents in the first step. After that, the treated bamboo was subjected to carboxymethylation and subsequently dissolved to form a transparent RTP film (B-film). The as-prepared B-film exhibited blue fluorescence and green phosphorescence, with an RTP lifetime reaching 547.77 ms. Moreover, this film possessed favorable processability and could efficiently transfer energy to Rhodamine B (RhB). As a result, a variety of multifunctional afterglow materials were fabricated by employing the B-film. Simultaneously, the luminescent film underwent rapid and complete biodegradation in soil within 15 days. This work is anticipated to provide a convenient strategy for producing sustainable RTP films from biomass resources.

竹制室温透明磷光膜

制造可持续室温磷光（RTP）薄膜而不依赖于固有的发色团是一个基本目标，但它仍然是一个持久的挑战。在这里，我们提出了一种有效的“自上而下”策略，直接将天然竹子转化为RTP薄膜。在此基础上，对天然竹材进行脱木质素处理，提取木质素成分。之后，处理过的竹子进行羧甲基化，随后溶解形成透明的RTP膜（b膜）。制备的b膜呈现蓝色荧光和绿色磷光，RTP寿命达到547.77 ms。该膜具有良好的可加工性，能有效地向罗丹明B （RhB）传递能量。利用b膜制备了多种多功能余辉材料。同时，发光膜在15 d内在土壤中迅速完全降解。这项工作有望为利用生物质资源生产可持续RTP薄膜提供一种方便的策略。
