Van-der-Waals transition metal dichalcogenides(vdW-TMDCs) layered materials have received huge attention due to their strong light-matter interaction. Moreover, combining 2D TMDCs with different organic materials opened a new line in heterostructure(Hs) research, providing unprecedented tunability for heterostructure(Hs) engineering. Few layers Pyrenemethylammonium chloride (PyMACL) is an emerging exfoliable organic material that offers distinct properties and could be attractive for photonic and optoelectronic applications. Here, we present our work on WS2/PyMACL vdW-HS. We have investigated our specimen using micro-photoluminescence and time-resolved photoluminescence shedding light on exciton dynamics in such structures, and possible recombination channels. Moreover, investigating possible charge transfer between the different layers of the Hs.
