In summary, we successfully demonstrated the area-selective ALD/MLD of Eu-organic thin films on single-layer graphene using fs-laser TPO to locally activate predefined regions. We achieved high homogeneity and over 90% selectivity for Eu-organic films up to 11 nm, overcoming the chemical inertness of graphene. The choice of polymer for graphene transfer significantly affected selectivity, as it might leave residues and promote undesired deposition on pristine graphene. The fabricated graphene/Eu-organic heterostructures exhibited strong PL emission upon 532 nm excitation, while Eu 3+ ions typically require UV excitation. Efficient electron and energy transfer via fluorescence quenching were demonstrated through work function, Raman, and fluorescence lifetime measurements at fs-laser doses above 160 pJ 2 s.
