In this work, an efficient method is developed to prepare silane‐functionalized red‐emissive carbon dots and carbon dots gel glasses with arbitrary loading fraction (0–100%). The as‐prepared materials possess strong photoluminescence and significant third‐order nonlinear optical performances. The optical properties can be tuned by either changing solvents and pH of the solution or adjusting the loading fractions of carbon dots in gel glasses. In particular, the photoluminescence of the carbon dots and their polymerized glasses can be linearly modulated from yellow to red emission by increasing the loading fraction of carbon dots or the polarity of solvent. It is also found that the chemical copolymerization leads to superior optical properties of gel glasses to that of the carbon dots solution, because the copolymerization endows stable immobilization of carbon dots in a rigid matrix. This study provides a feasible method to prepare optoelectronic hybrid materials and devices.

可聚合碳点及其任意共聚凝胶玻璃的可控光致发光和非线性光学性质

在这项工作中，开发了一种有效的方法来制备硅烷官能化的红色发光碳点和凝胶点状玻璃，并具有任意的填充率（0–100％）。所制备的材料具有很强的光致发光性和显着的三阶非线性光学性能。可以通过改变溶液的溶剂和pH值或调整凝胶玻璃中碳点的负载比例来调节光学性能。特别地，通过增加碳点的负载比例或溶剂的极性，可以将碳点及其聚合玻璃的光致发光从黄色发射线性地调制为红色发射。还发现，化学共聚可导致凝胶玻璃的光学性能优于碳点溶液的光学性能，因为共聚能将碳点稳定地固定在刚性基质中。该研究为制备光电混合材料和器件提供了一种可行的方法。
