Structural, optical and photocatalytic properties of Ce-doped SnS2 nanoflakes

Electronic structures of SnS and SnS2

“…Different types of nanomaterials have been obtained including nanosheets and nanoplates , nanoflowers , nanoflakes , three‐dimensional hierarchical microspheres , nanowalls , nanotubes and graphene anchored SnS 2 . There are many other uses of SnS 2 especially in photocatalysis , as photoconductors , photoluminescence devices , photodetectors or field‐effect transistors , gas sensors and solar cells .…”

Molybdenum-doped few-layered SnS2 architectures with enhanced electrochemical supercapacitive performance

“…For instance, Ce doped SnS 2 material demonstrates obviously enhanced Li storage performance due to the fact that Ce doping can stabilize the crystal lattice during charge/discharge and improved photocatalytic effect for the modied electronic structure of SnS 2 . 43,44 Doping SnS 2 with copper can increase the carrier density and the optical absorption and makes the photocatalytic process more efficient. 45 However, to our knowledge, the investigation of SnS 2 nanostructures as a supercapacitor electrode is seldom and the electrochemical properties of SnS 2 for pseudocapacitors still need to be further investigated.…”

Effect of carrier gas pressure on structural, optical and photovoltaic properties of tin sulphide thin films prepared by nebulizer spray pyrolysis method

“…For excitation at 550 nm, an intense peak was observed at about 825 nm, corresponding to energy ∼ 1.50 eV which may be due to near band edge emission and is a little higher than the band gap estimated from UV-Vis data. The PL spectra did not exhibit any deep level emission peaks which confirm that the prepared SnS thin films did not have any defects [41]. The origin of a sharp emission peak around 825 nm is due to the emission from vacancies and that of defects which are essential for growth, i.e., interstitial and stacking faults.…”
