pH dependent tunable photoluminescence of Polyaniline grafted Graphene Oxide (GO–PANI) nanocomposite
Prosenjit Saha,Dinesh Kumar Pyne,Madhubonti Pal,Sudeshna Datta,Prabir Kumar Das,Partha Dutta,Arnab Halder +6 more
TL;DR: Aqueous dispersion of GO-PANI (pH=4.6) shows dual fluorescence at 345 nm and 405 nm upon excitation at 280 nm indicating the presence of two emissive moieties as mentioned in this paper.

Effect of an anionic surfactant (SDS) on the photoluminescence of graphene oxide (GO) in acidic and alkaline medium
Prosenjit Saha,Dinesh Kumar Pyne,Srijon Ghosh,Soumadip Banerjee,Sourav Das,Soumen Ghosh,Partha Dutta,Arnab Halder +7 more
TL;DR: In this article, anionic surfactant (SDS) modulates the photoluminescence of graphene oxide (GO) in both acidic and alkaline medium, leading to a significant 36 nm blue shift of the luminance band, whereas SDS interacts with GO sheets in a different way due to the presence of negatively charged carboxylate ions at the GO edges.
Photoluminescence amplification of cerium incorporated graphene oxide nanoparticles by photoinduced reduction: A mechanistic study highlighting structural orderness
TL;DR: In this article, a simple one pot synthesis of enormously luminescent cerium ion incorporated graphene oxide nanoparticles (GO-Ce NPs) was proposed to overcome the limitation of weakly luminescence graphene oxide (GO) based materials.

Tunable luminescence of graphene oxide-polyaniline nano-composite: Effect of an anionic surfactant
TL;DR: In this article, the luminescence of the graphene oxide-polyaniline (GO-PANI) nano-composite has been found to be tuned in the presence of an anionic surfactant (sodium dodecyl sulphate, SDS).
