Pyrylium ion (CHO)-based salts exhibit distinctive optical properties that can be tuned by external stimuli such as temperature and pressure, making them suitable materials for various nanoscale optoelectronic applications. However, their practical use has been limited by their solid powder form, which poses challenges for integration into realistic devices. Herein, we present a low-temperature, post-melting encapsulation method for the incorporation of a 2,4,6-triphenylpyrylium chloride salt within transparent phosphate glasses containing dispersed silver nanoparticles. This synthesis approach enables spatially controlled vitrification of high-refractive index pyrylium pathways within the glass matrix. The encapsulated salt retains its structural and optical properties, while the presence of randomly dispersed silver nanoparticles enhances light transmission upon scattering effects. The resulting pyrylium salt-glass composites exhibit robust waveguiding characteristics, positioning this technique as a promising route for the fabrication of advanced nano-engineered optoelectronic devices.
基于吡喃鎓离子（CHO）的盐具有独特的光学性质，可通过温度和压力等外部刺激进行调节，使其成为适用于各种纳米级光电器件应用的材料。然而，它们的实际应用受到其固体粉末形式的限制，这给集成到实际器件中带来了挑战。在此，我们提出了一种低温后熔融封装方法，用于将2,4,6-三苯基氯化吡喃鎓盐掺入含有分散银纳米颗粒的透明磷酸盐玻璃中。这种合成方法能够在玻璃基质内实现高折射率吡喃鎓通道的空间控制玻璃化。封装的盐保留了其结构和光学性质，而随机分散的银纳米颗粒的存在通过散射效应增强了光传输。所得的吡喃鎓盐-玻璃复合材料表现出强大的波导特性，将该技术定位为制造先进纳米工程光电器件的一条有前途的途径。
