What does "at%" refer to in sol-gel method? I'm reading on the preparation of ZnO thin films for UV stimulated emission and I found a method called Sol-Gel. During this I found a paragraph saying, " the ration Ag/Zn in the sol is 3 at%......". so I want to know what at% refer to.
Atomic percentage. It can be converted to weight percentage (wt%) too.
