Nanophotonics is one of the most important branches of electronics. The search for and design of novel and more efficient laser-operated materials seems to be fully justified. Therefore, here, we show how to fabricate materials that have an enhanced non-linear optical response using a procedure of synthesis in a silica nanoreactor. We obtained the initial material through the precise functionalisation of SBA-15 silica using nickel phosphonate units that were anchored inside the silica channels by propyl chains, which was then transformed into an optically active nanocomposite after thermal processing. Using thermogravimetry, transmission electron microscopy (TEM), Raman vibrational analysis, and N${}_2$ sorption analysis, we analysed the thermal behaviour of the initial functional material. All research that is connected with second- and third-order optical harmonic generation enables the structural changes in these materials and their influence on their optical properties to be explored. Nonlinear optical measurements confirmed our assumption that material that is prepared using silica nanoreactors can have precisely tailored properties, in this case, nonlinear optical properties.

纳米光子学是电子学中最重要的分支之一。寻找和设计新颖，更高效的激光操作材料似乎是完全合理的。因此，在这里，我们展示了如何使用二氧化硅纳米反应器中的合成程序来制造具有增强的非线性光学响应的​​材料。我们通过使用膦酸镍单元通过丙基链锚定在二氧化硅通道内，通过对SBA-15二氧化硅进行精确功能化来获得初始材料，然后在热处理后将其转化为光学活性纳米复合材料。使用热重分析，透射电子显微镜（TEM），拉曼振动分析和N${}_2$吸附分析，我们分析了初始功能材料的热行为。所有与二阶和三阶光学谐波产生相关的研究都可以探讨这些材料的结构变化及其对光学性能的影响。非线性光学测量证实了我们的假设，即使用二氧化硅纳米反应器制备的材料可以具有精确定制的特性，在这种情况下，可以是非线性光学特性。
