Effect of stabilizer on preparation of silver and gold nanoparticle using grinding method

Silver and gold nanoparticles were prepared by grinding method using stabilizers such as de-ionized water, ethylene glycol (EG) and 5 wt% polyvinyl alcohol (PVA). From the observation, it was found that the solution's color of silver particle changed from clear color to light yellow or brown an...

It was found that the absorbance and transmission spectra of silver and gold nanoparticles depended on the type of stabilizing agent and grinding time. In addition, the observed color of nanoparticles could be explained using Maxwell triangle and in agreement with the color observed by naked eyes. 2014-08-30T02:56:40Z 2014-08-30T02:56:40Z 2008 Article 01252526 http://www.scopus.com/inward/record.url?eid=2-s2.0-67650317768&partnerID=40&md5=c10e2ba05e0b75ec0312c11dfe8c57be http://cmuir.cmu.ac.th/handle/6653943832/5565 English
