    • A method of assembling superparamagnetic colloids into ordered structures with magnetically tunable photonic properties in nonpolar solvents by establishing long-range electrostatic repulsive forces using charge control agents. Reverse micelles resulted from the introduction of charge control agents such as AOT molecules can enhance the charge separation on the surfaces of n-octadecyltrimethoxysilane modified Fe 3 O 4 @SiO 2 particles. The significantly improved long-range electrostatic repulsion can counterbalance the magnetically induced attraction and therefore allow ordering of superparamagnetic colloids in nonpolar solvents. This system possesses fast and fully reversible optical response to the external magnetic fields, long-term stability in performance, and good diffraction intensity.
    • 通过使用电荷控制剂建立远程静电排斥力,在非极性溶剂中将超顺磁性胶体组装成具有磁可调谐光子性质的有序结构的方法。 由引入电荷控制剂例如AOT分子而产生的反胶束可以增强正十八烷基三甲氧基硅烷改性的Fe 3 O 4 :SiO 4表面上的电荷分离, 2颗粒。 显着改善的远程静电斥力可抵消磁诱导吸引力,因此允许在非极性溶剂中排序超顺磁性胶体。 该系统对外部磁场具有快速和完全可逆的光学响应,长期稳定的性能和良好的衍射强度。

    • The production of photocatalytic color switching of redox imaging nanomaterials for rewritable media is disclosed. The new color switching system is based on photocatalytic redox reaction enabling reversible and considerably fast color switching in response to light irradiation. In accordance with an exemplary embodiment, the color switching system can include a photocatalyst and an imaging media. With the assistance of photocatalyst, UV light irradiation can rapidly reduce the redox imaging nanomaterials accompany with obvious color changing, while the resulting reduced system can be switched back to original color state through visible light irradiation or heating in air condition. The excellent performance of the new color switching system promises their potential use as an attractive rewritable media to meet increasing needs for sustainability and environmental protection.

    • Alloyed Ag/Au nanospheres with high compositional homogeneity ensured by annealing at elevated temperatures show large extinction cross-sections, extremely narrow band-widths and remarkable stability in harsh chemical environments. Nanostructures of Ag are known to have much stronger surface plasmon resonance than Au, however, their applications in many areas have been very limited due to their poor chemical stability against non-ideal chemical environment. Fully alloyed Ag/Au nanospheres are produced through a surface-protected annealing process. A critical temperature has been found to be around 930°C, below which the resulting alloy nanospheres, although significantly more stable than pure silver nanoparticles, can still gradually decay upon extended exposure to harsh etchant. The nanospheres annealed above the critical temperature show homogeneous distribution of Ag and Au elements, minimal crystallographic defects, absence of structural and compositional interfaces, which account for the extremely narrow bandwidths of the surface plasmon resonance, and may render many plasmonic applications with high performance and long lifetime, especially for those involving corrosive species.
    • 通过在高温下退火确保的具有高组成均匀性的合金Ag / Au纳米球显示出大的消光截面,极窄的带宽和在恶劣的化学环境中的显着的稳定性。 已知Ag的纳米结构具有比Au更强的表面等离子体共振,然而,由于其对非理想化学环境的化学稳定性差,其在许多领域的应用非常有限。 通过表面保护退火工艺生产完全合金化的Ag / Au纳米球。 已经发现临界温度为约930℃,低于此温度时,所得合金纳米球尽管比纯银纳米颗粒显着更稳定,但是在延长暴露于苛刻蚀刻剂的情况下仍可逐渐衰减。 在临界温度以上退火的纳米球体显示Ag和Au元素的均匀分布,最小的晶体缺陷,不存在结构和组成界面,这导致表面等离子体共振的极窄带宽,并且可能使许多等离子体激元应用具有高性能和 使用寿命长,尤其适用于腐蚀性物质。
