A transparent fluoroborosilicate glass ceramic was designed for the controllable precipitation of fluoride nanocrystals and to greatly enhance the photoluminescence of active ions. Through the introduction of BO into fluorosilicate glass, the melting temperature was decreased from 1400 to 1050 °C, and the abnormal crystallization in the fabrication process of fluorosilicate glass was avoided. More importantly, the controlled crystallizations of KZnF and KYbF in fluoroborosilicate glass ceramics enhanced the emission of Mn and Mn-Yb dimers by 6.7 and 54 times, respectively. Moreover, the upconversion emission color of glass ceramic could be modulated from yellow to white and blue by adjusting the Yb concentration. The well-designed glass ceramic is a novel and significant compound to simultaneously provide efficiently coordinated sites for transition metal and rare earth ions. More importantly, the design strategy opens a new way for engineering high-quality oxy-fluoride glass ceramics with properties of excellent stability, controllable nano-crystallization and high-efficiency photoluminescence.
设计了一种透明氟硼硅酸盐玻璃陶瓷，用于可控沉淀氟化物纳米晶体，并极大增强活性离子的光致发光。通过将BO引入氟硅酸盐玻璃中，熔融温度从1400℃降至1050℃，避免了氟硅酸盐玻璃制造过程中的异常结晶。更重要的是，氟硼硅酸盐玻璃陶瓷中KZnF和KYbF的可控结晶分别使Mn和Mn-Yb二聚体的发射增强了6.7倍和54倍。此外，通过调节Yb浓度，玻璃陶瓷的上转换发射颜色可从黄色调制为白色和蓝色。精心设计的玻璃陶瓷是一种新颖且重要的化合物，能同时为过渡金属和稀土离子提供高效配位位点。更重要的是，该设计策略为制造具有优异稳定性、可控纳米结晶和高效光致发光特性的高质量氧氟化物玻璃陶瓷开辟了一条新途径。
