） 和 Tuan Vo-Dinh （Gold Nanostars For Surface-Enhanced Raman Scattering:
Synthesis, Characterization and Optimization）的方法合成，怎么都出不来啊。只
能得到球星的大颗粒，没有任何长出branch 或者tip的迹象。有做过的能给点指导吗。

nanoporous silica as template, maybe Au nano particles can form inside the
template. Silica can be easily removed by HF.
Nano particles are very fun! I never forgot the day I saw 5 nm ZnO I made
under TEM.
Let me know if the method works.
Good luck! |
