I have preapared a solution of TMB Hydrogen peroxide and Graphene oxide it is not showing any colour.Why?

The literature reveals that this solution should have blue colour as H2O2 oxidizes TMB. I dont know what went wrong why there is no colour? what can be the possible reasons?

If as prepared graphene oxide is excited at shorter wavelength in Raman spectroscopy, what can we infer about its energy states and hence its purity?

I prepared graphene oxide and it showed results at short wavelength of 457 nm but other students got results at 514 nm. so i want to know about the enrgy states and quality of my sample?
