Unraveling the Role of Interfacial Charge Transfer on Photoactivity and Anomalous Luminescence Quenching of V₄C₃T<i>_<i>x</i></i>/Protonated g-C₃N₄ Heterostructures.

ABSTRACT: Two-dimensional van der Waals heterostructures with exotic quantum phenomena have garnered a huge surge in the field of optoelectronic devices. Herein, we report spectroscopic evidence of efficient interfacial charge transfers at the interface of a novel 2D/2D V₄C₃T_x MXene/protonated g-C₃N₄ (PCN) heterostructured thin film, demonstrating robust photosensitivity and a large exciton activation energy of 139.5 meV. Through temperature-dependent photoluminescence (PL) and time-resolved PL spectroscopy, we unravel the photophysical mechanism driving efficient charge transfer and photosensitivity in V₄C₃T_x/PCN heterostructures. These heterostructures exhibit superior photosensitivi
