In the following paper the reported that normal hummers method and modified hummers method that is not only prepare GO but also formed the hydrophobic materials in high quantity how to seperate our pure GO from the bulk.
For calculating quantum yield measurement what should be used as standard reference excitation 510 to 530 nm or emission 700-800 nm? Please explain anyone. For my compound i am getting emission at...
