摘要/Abstract

摘要： 本研究创新性地提出了一种基质比例调控策略，通过一步水热法合成了可调谐白色室温磷光(RTP)碳点嵌入三氧化二硼(B₂O₃)与三聚氰酸(CA)双限域复合材料(记为W-CD@B₂O₃-CA)。通过调节基质比例并利用多重限域效应，所获得的W-CD@B₂O₃-CA实现了从暖白光到中性白光、再到冷白光的宽范围色度调控，显色指数从85.6提升至91.1。系统表征表明，白色余辉发射源于碳核尺寸、表面官能团及基质内B/N共掺杂的协同贡献。基于其独特的光学特性，成功开发了高对比度指纹识别与多级信息加密应用。此外，通过优化合成工艺，实现了低成本、高产率的公斤级制备，为新型高效白色RTP材料的实际探索提供了新路径。

Abstract: This study innovatively proposes a matrix proportion regulation strategy to synthesize tunable white room-temperature phosphorescent (RTP) carbon dots embedded B₂O₃-cyanuric acid (CA) dual-confinement composites (denoted W-CD@B₂O₃-CA) via a one-step hydrothermal method. By modulating the matrix ratio and utilizing the multiple confinement effect, the obtained W-CD@B₂O₃-CA achieve wide-range chromaticity tuning from warm white light to neutral white light, and further to cold white light. The color rendering index is elevated from 85.6 to 91.1. Systematic characterizations indicate that the white afterglow emission originates from the synergistic contribution of carbon core size, surface functional groups, and B/N co-doping within the matrix. Based on their unique optical properties, high-contrast fingerprint recognition and multi-level information encryption applications have been successfully developed. Furthermore, by optimizing the synthesis process, kilogram-scale preparation has been achieved with low cost and high yield, offering a novel pathway for the practical exploration of new, efficient white-light RTP materials.

Key words: Tunable white-light afterglow carbon dots composites, Kilogram-scale synthesis, Multiple confinement effects, Fingerprint imaging, Information encryption
