In this paper, we report UV photocurrent response of 2D hybrid materials consisting of layered WS2 nanosheets and reduced graphene oxide prepared by using one step hydrothermal method. Few-layer WS2 and WS2/RGO nanosheets are characterized by Raman spectroscopy and HRTEM. The electric and optoelectronic properties of WS2 and WS2/RGO based UV photodetector shows a fast response of 48s and 85s and high photosensitivity (80 mu AW(-1) and 3.21 mAW(-1)) indicating that the two-dimensional composite nanostructure WS2/RGO is an important material for high performance photodetectors.

MoS2 nanosheets were prepared through a facile hydrothermal method with different reaction temperatures. The as-synthesized MoS2 nanosheets were characterized with XRD, SEM, TEM, and Raman spectroscopy, which confirmed successful preparation and rationality. Further, the humidity dependent electrical properties against relative humidity (RH) of these samples were carried out at room temperature. The results evinced that the sensors film fabricated with MoS2 nanosheets prepared at temperature 220 degrees C exhibited better performance compared to the nanosheets synthesized at 180 degrees C and 200 degrees C temperature. The RH sensing results exhibits highly sensitive, ultrafast response/recovery behaviour and outstanding repeatability than reported earlier. The excellent humidity sensing properties of the resultant MoS2 nanosheets was proved to be an excellent candidate for constructing ultrahigh-performance humidity sensor toward various applications.</p>10aHumidity sensors10aHydrothermal method10aMolybdenum Disulphide10ananosheets1 aShelke, Nitin, T.1 aKarle, S., C.1 aKarche, B., R.  uhttps://library.ncl.res.in/content/hydrothermal-growth-and-humidity-dependent-electrical-properties-molybdenum-disulphide
