Rational design and fabrication of multicolor fluorescent sources represent one of the significant challenges in the development of high‐performance solid‐state lighting, tunable coherent lasing, and full‐color display technologies. However, generation of simultaneous multicolor emission, especially white light generation with a wide color gamut is usually beyond the ability of a single material. Heterogeneous structures made by combinations of red, green, and blue emission building blocks are bulky, inefficient, complicated, and costly. Here reported is a bottom‐up strategy to generate simultaneous multicolor emission with continuous tunability in a single monolithic material based on the “nanocrystals‐in‐glass composite” (NGC) architecture. In this approach, a self‐sustained low‐temperature solution combustion process enables homogeneous solvent dispersion and eventually stable immobilization of multiple nanocrystals in transparent matrix. With transparency of up to 80%, further demonstrated is drawing of fiber from the melt of these combustion‐processed NGC materials. The optical spectra of the as‐drawn glass fiber can be precisely tuned and clustering is effectively suppressed. Moreover, the NGC materials exhibit remarkable anti‐thermal quenching behavior at temperatures of up to 200 °C. The bottom‐up strategy for NGC provides a versatile platform for the fabrication of high‐performance multifunctional fiber‐based devices for advanced applications in lasers, illumination, displaying, and biophotonics.

溶液燃烧法制备的透明纳米晶玻璃复合材料的发射颜色操纵

合理设计和制造多色荧光灯源是高性能固态照明，可调谐相干激光和全色显示技术发展中的重大挑战之一。然而，同时发色的产生，尤其是具有宽色域的白光的产生通常超出了单一材料的能力。由红色，绿色和蓝色发射构建块组合而成的异质结构体积庞大，效率低下，复杂且昂贵。本文报道了一种自下而上的策略，该方法基于“玻璃中纳米晶体”（NGC）架构，在单一的整体材料中同时产生具有连续可调性的多色发射。用这种方法 一个自我维持的低温溶液燃烧过程可以使溶剂均匀分散，并最终将多个纳米晶体稳定地固定在透明基质中。透明性高达80％，进一步证明了从这些燃烧处理过的NGC材料的熔体中提取纤维。可以精确调整玻璃纤维的光谱，并有效抑制聚集。此外，NGC材料在高达200°C的温度下表现出出色的抗热淬火性能。NGC的自下而上的策略为制造高性能多功能光纤设备提供了一个通用平台，该设备可用于激光，照明，显示和生物光子学的高级应用。透明性高达80％，进一步证明了从这些燃烧处理过的NGC材料的熔体中提取纤维。可以精确调整玻璃纤维的光谱，并有效抑制聚集。此外，NGC材料在高达200°C的温度下具有出色的抗热淬火性能。NGC的自下而上的策略为制造高性能多功能光纤设备提供了一个通用平台，该设备可用于激光，照明，显示和生物光子学的高级应用。透明性高达80％，进一步证明了从这些燃烧处理过的NGC材料的熔体中提取纤维。可以精确调整玻璃纤维的光谱，并有效抑制聚集。此外，NGC材料在高达200°C的温度下表现出出色的抗热淬火性能。NGC的自下而上的策略为制造高性能多功能光纤设备提供了一个通用平台，该设备可用于激光，照明，显示和生物光子学的高级应用。NGC材料在高达200°C的温度下具有出色的抗热淬火性能。NGC的自下而上的策略为制造高性能多功能光纤设备提供了一个通用平台，该设备可用于激光，照明，显示和生物光子学的高级应用。NGC材料在高达200°C的温度下具有出色的抗热淬火性能。NGC的自下而上的策略为制造高性能多功能光纤设备提供了一个通用平台，该设备可用于激光，照明，显示和生物光子学的高级应用。
