How can I determine the number of layers of Graphene oxide from its Raman spectrum? I saw some papers saying it can be done using the values of the D band (and not 2D) and G band, but how do you exactly do that? Is there any specific formula for it?
I wanted to get the numbers of layers or a range of it so (https://instanano.com/characterization/calculator/raman/graphene-layers/) wasn't very helpful!
