The ability of nanoscale materials to trap electromagnetic field beyond the diffraction limit is seldom studied using multifunctional nanohybrids. To this end, we demonstrate a thermo-migratively assembled Soret nanoassembly that enable unique metal-metal, metal-graphene and metal-dielectric resonances. In contrast to the well-explored standalone plasmonic and dielectric platforms, the Soret colloids possess salient nanogaps that exhibit delocalized Bragg and localized Mie plasmon resonances with effective EM field confinement. Accordingly, the Soret colloids of silver metal with plasmonic NPs: platinum (AgPtSC), 2D material: graphene oxide (AgGOSC) and dielectric NPs: TiC (AgTiCSC), TiN (AgTiNSC) and TiCN (AgTiCNSC) comprehensively have been utilized to achieve >600-fold fluorescence enhancements. The ability to tailor the highly directional and p-polarized emission enhancements using these well-characterized multifunctional sorets has been experimentally demonstrated on surface plasmon-coupled emission (SPCE) platform. The mobile phone-based detection of environmentally relevant Cu²⁺ ions in drinking water using AgPtSC presents low-cost, rapid, simple, sensitive and reliable sensing strategy for Cu²⁺ ion monitoring in resource-limited settings. Further, dye-degradation of xenobiotic pollutants for environmental remediation presents multifarious applications with these nano-architectures. This study opens a new window to explore synergy of nanomaterials constituting elements from different parts of periodic table to accomplish essential properties for desired applications.

很少使用多功能纳米杂化材料来研究纳米级材料捕获超出衍射极限的电磁场的能力。为此，我们演示了热迁移组装的Soret纳米组件，该组件能够实现独特的金属-金属，金属-石墨烯和金属-介电共振。与经过充分研究的独立等离子和电介质相反因此，Soret胶体具有显着的纳米间隙，在有效的EM场约束下，它们表现出离域的Bragg和局域的Mie等离子体激元共振。因此，具有等离子NP：铂（AgPtSC），二维材料：氧化石墨烯（AgGOSC）和电介质NP：TiC（AgTiCSC），TiN（AgTiNSC）和TiCN（AgTiCNSC）的银金属的Soret胶体已被广泛用于实现> 600倍荧光增强。在表面等离激元耦合发射（SPCE）平台上已通过实验证明了使用这些功能完备的多功能soret量身定制高方向性和p极化发射增强的能力。基于手机的环境相关Cu ^2+的检测使用AgPtSC的饮用水中的离子提供了一种低成本，快速，简单，灵敏和可靠的传感策略，用于在资源受限的环境中监测Cu ²⁺离子。进一步地，用于环境修复的异生物污染物的染料降解在这些纳米结构中呈现了多种应用。这项研究打开了一个新的窗口，以探索构成元素周期表不同部分的纳米材料的协同作用，以实现所需应用的基本性能。
