Excitation-dependent/ independent emission of carbon dots?

05 May 2019 1 3K Report

Hi experts.. Can you explains why the excitation-“dependent” emission of aqueous N-CDs suddenly changed to ”independent” while binding with PVA (solid film). Is this related to PVA nature? Please help And thanks in advance.
