Developing fluorescence switching as functional system is highly desirable for potential applications in the fields of light-responsive materials or devices. Attempt to construct fluorescence switching system tend to focus on the high fluorescence modulation efficiency, especially in solid state. Herein, a photo-controlled fluorescence switching system was constructed with photochromic diarylethene and trimethoxysilane modified zinc oxide quantum dots (Si-ZnO QDs) successfully. It was verified by the measurement of modulation efficiency, fatigue resistance as well as theoretical calculation. Upon irradiation with UV/Vis lights, the system exhibited excellent photochromic property and photo-controlled fluorescence switching performance. Furthermore, the excellent fluorescence switching characters could also be realized in solid state and the fluorescence modulation efficiency was determined to be 87.4%. The results will provide new strategies to the construction of reversible solid-state photo-controlled fluorescence switching for the application in the fields of optical data storage and security labels.
开发荧光开关作为功能系统对于光响应材料或器件领域的潜在应用非常有必要。构建荧光开关系统的尝试往往集中在高荧光调制效率上，尤其是在固态情况下。在此，成功构建了一种由光致变色二芳基乙烯和三甲氧基硅烷修饰的氧化锌量子点（Si-ZnO QDs）组成的光控荧光开关系统。通过调制效率、抗疲劳性测量以及理论计算对其进行了验证。在用紫外/可见光照射时，该系统表现出优异的光致变色性能和光控荧光开关性能。此外，在固态下也能实现优异的荧光开关特性，荧光调制效率测定为87.4%。这些结果将为构建用于光学数据存储和安全标签领域的可逆固态光控荧光开关提供新策略。
