Transparent glasses are ideal and robust hosts for a range of emission centers, while the simultaneous manipulation of the temporal and spectral characteristics of emission remains a tremendous challenge for inorganic glasses. Here, the development and functionalization of melt-quenched transparent coordinate polymer glasses with a tailorable ultralong room-temperature phosphorescence are demonstrated. Dynamic modulation of the phosphorescence is achieved by utilization of the high molecular rigidity and manipulation of the spin-orbital coupling effects within the glass systems. By introducing dye molecules into the glasses, Phosphorescence resonance energy transfer from the glass matrix to the dye molecules is exploited and controllable multicolor long-lived luminescence is demonstrated. Further design of the component and concentration of the encapsulated dyes allows for wavelength-tunable long-lived delayed fluorescence via an efficient delayed sensitization process, featuring a tunable emission spectrum covering a wide range from 520 to 630 nm. Leveraging the multiple spectral tuning channels of the hybrid glass, multi-mode optical information storage, and dynamic anti-counterfeiting applications are further demonstrated. This work provides a new hybrid material platform and design methodology for realizing lifetime-adjustable and wavelength-tunable long-lived luminescence, which can find wide applications in time-rsesolved information display, high-density information storage, and dynamic anti-counterfeiting.

基于熔体淬火玻璃态金属有机配合物的超长磷光的光谱和时间操控，实现多模光子功能
透明玻璃是一系列发射中心理想且坚固的宿主，而同时控制发射的时间和光谱特性仍然是无机玻璃的巨大挑战。在这里，展示了具有可定制超长室温磷光的熔融淬火透明配位聚合物玻璃的开发和功能化。通过利用玻璃系统内的高分子刚性和自旋轨道耦合效应的操纵来实现磷光的动态调制。通过将染料分子引入玻璃中，利用了从玻璃基质到染料分子的磷光共振能量转移，并证明了可控的多色长寿命发光。封装染料的成分和浓度的进一步设计允许通过有效的延迟敏化过程实现波长可调的长寿命延迟荧光，其具有覆盖 520 至 630 nm 的宽范围的可调发射光谱。利用混合玻璃的多个光谱调谐通道，进一步展示了多模光学信息存储和动态防伪应用。这项工作为实现寿命可调和波长可调的长寿命发光提供了一种新的混合材料平台和设计方法，可在时间分辨信息显示、高密度信息存储和动态防伪等领域得到广泛应用。
