what is the effect of thickness on spectrum peak profile, position and until which thickness, this effect would be detectable?

Hassan Alshamsi

The properties of graphene can depend on the number of layers.π→ π* transition in all mono,bi and multilayer graphene associates with peak appears near or at 270 nm.Optical transparency depends on the fine structure and number of graphene layers . The following references may be helpful :

Could we get the spec of graphene sheets 270nm, in benzene (UV cut-off >300), using reference spec of solvent or we must exchange solvent medium?

My experiments show that even by using reference spectrum of the solvent, it is not possible to get a valid and correct spectrum using solvents with a UV cut-off of moe than characteristic peak
