同样的,在玻璃氟氧化物玻璃组成成分中掺入稀土离子和(Ag、Au或其他金属离子),对玻璃片进行热处理,使得氟氧化物微晶和金属纳米颗粒或团簇同时析出,此时所析出的金属纳米颗粒或团簇会分散于微晶周围,甚至附着于微晶表面,此时,我们可以通过调控玻璃内部网络结构来调控金属纳米颗粒尺寸、分散情况以及与微晶之间的关系等等,从而研究微晶玻璃中的SPR现象。
Similarly, the incorporation of rare earth ions , together with Ag, Au or other metal ions in fluorine oxide glass, followed by heat treatment on the glass pieces, led to the simultaneous formation of microcrystals of fluorine oxide and metal nanoparticles or aggregates, with the metal nanoparticles or aggregates distributed among microcrystals, or even attached to the surface of these microcrystals. In the process we can control the sizes of nanoparticles, their distribution and their relationship to the microcrystals through the control of internal structure of glass, which provides us a tool to study the SPR phenomenon in microcrystal glasses. |
