ABSTRACT = {Cu<sub>2</sub>ZnSnS<sub>4</sub> nanocrystals (CZTS NCs), MoS<sub>2</sub> nanosheet (NS) and MoS<sub>2</sub>-CZTS 
nanocomposite (NC) have been synthesized using solvothermal route. Structural 
characterization of samples have been done by XRD, Raman spectroscopy, HR-TEM. 
Samples have optically characterized by UV-Vis absorption, photoluminescence (PL) and 
time co-related single photon counting (TCSPC) study. The XRD, HR-TEM and Raman 
spectroscopy established tetragonal kesterite phase for both CZTS NCs and MoS2-CZTS 
NC. Enhancement of efficiency of CZTS NCs to degrade methylene blue (MB) dye, 
illuminated by visible light, have been observed by loading 1 wt.% MoS<sub>2</sub> NS and found to 
be ~100% in only 15 minutes. This is due to efficent transfer of charge carriers at p-CZTS 
and n-MoS<sub>2</sub> heterojunction interface, confirmed by quenching of PL intensity and decrease 
in average lifetime of carriers. },
