此时我们是否可以事先在玻璃组分中掺入少量一些形核剂,在二次玻璃热处理析出纳米晶粒时,同时外加强磁场,使得所析出的金、银纳米颗粒呈现椭圆形,甚至形成纳米棒状,而纳米棒金纳米棒可以实现对放大的SPR波长的灵活调节以及独特的各向异性偏振特性,甚至我们可以通过变换磁场方向来控制玻璃中所析出很小纳米尺寸的形状,最终调节金属纳米颗粒的共振吸收波长。

We wonder if we can incorporate a small amount of nucleation agent to the glass, and an external strong magnetic field will be applied at  the secondary heat treatment step during which nanoparticles start to form. The resulting gold and silver nanoparticles might form in ecliptic or rod shape. It is known that gold  nanorods can be used to amplify and flexibly adjust the wavelength of SPR, and they possess a unique anisotropic polarization property.  Our attempt to control the shape of nanoparticles in glass through external magnetic field may allow us to regulate (or tune) the wavelength of resonance that originated from these metal nanoparticles.
离成功还差一点
