Organic phosphorescence glass has garnered considerable attention owing to the excellent shaping ability and photophysical behavior, but facile construction from single-component phosphors is still challenging. Herein, a rigid-soft coupling design is adopted in organic phosphors of ICO, CCO and PCO, thus preparing phosphorescence glasses through melting-quenching method to give excellent shaping ability and dynamic phosphorescence. RTP performance is significantly enhanced in the dense-structure glass, and intriguing high-temperature phosphorescence (HTP) is still observable even at 400 K. Direct patterning under UV irradiation is also achieved using photolithography technique, allowing for the creation of high-quality afterglow patterns that can be reversibly erased and rewritten. This rigid-soft conformation in organic phosphors elucidates a promising concept for achieving efficient RTP glass with wide application prospects.
有机磷光玻璃因其出色的成型能力和光物理行为而备受关注，但由单一组分磷光体轻松构建仍具有挑战性。在此，在ICO、CCO和PCO的有机磷光体中采用了刚性-柔性耦合设计，通过熔融淬火法制备磷光玻璃，以赋予其出色的成型能力和动态磷光。在致密结构玻璃中，室温磷光（RTP）性能显著增强，甚至在400 K时仍可观察到有趣的高温磷光（HTP）。使用光刻技术还可在紫外光照射下直接进行图案化，从而创建可可逆擦除和重写的高质量余辉图案。有机磷光体中的这种刚性-柔性构象阐明了一种实现具有广泛应用前景的高效RTP玻璃的有前景的概念。
