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。
