Cellulose-based room temperature phosphorescent gels with ultra-strong hydrogen-bonded networks driven by phase separation for advanced anti-counterfeiting.

Room temperature phosphorescent (RTP) hydrogels have garnered extensive attraction owing to their distinctive optical properties, low toxicity and cost-effectiveness. However, achieving efficient and long-lived afterglow emission in hydrogel systems remains a formidable challenge due to the severe quenching of triplet...
