“…The first peak at 625-629 nm region was originated from the deep level emissions (DLE) that mostly created by crystalline defects in the crystal lattices such as interstitial and stacking faults. [36,37] But a red shift in NBE emission bands can be related to altering the energy band due to the presence of Se ions. [32] Two band emission peaks located at 706-712 nm and 748-749 nm are probably caused by the free-carrier and/or excitonic band edge transitions between the valence band and the conduction band.…”

Un-and Se-doped nanostructured SnS thin films were synthesized (deposited) on FTO-coated glass substrates using an electrodeposition method. A study of the crystallinity indicated an orthorhombic phase with a grain size of 54-75 nm. Morphological features of the films showed a well-developed rod structure (less than 100 nm). Optical energy band gaps in the range of 1.26-1.46 eV were estimated for the deposited films. The effect of Se as a dopant on the determination of the optoelectronic and conductivity conversion from p-to n-type nanostructured SnS thin films was investigated. In addition, an n-type Se-SnS film was obtained at lower concentrations of Se. This technique is suggested to control the electrical conductivity of deposited films to be applied in photoswitching-based devices.

“…The blue shift in band emissions is probably caused by the size of nanostructures created on the surface of films. [36,37] But a red shift in NBE emission bands can be related to altering the energy band due to the presence of Se ions. [22] The measurement of optical absorbance was performed on deposited films.…”

“…Even though our hierarchical morphology is different from any one in the literature (microsphere or microtube decorated with nanostructure), we have done a comparison of our results with a couple of references with the same composition (SnS and ZnS) ,,,,,. A table has been created (see Supporting Information, table 1S) comparing the mass of the catalytic material, the initial concentration of the methylene blue, the degradation of the MB after 90 minutes, and the morphology of structure used in each work.…”

SnS and ZnS hollow microarchitectures decorated with nanostructures were synthesized by catalysis free thermal evaporation technique using metal microwires and sulfur powder as starting materials. For SnS, we observed a microtube formation comprised of a thin metallic Sn layer in the inner surface, SnS orthorhombic structure thick layer with SnS nanostructures on the top. For ZnS, we found out the formation of hollow sphere with a thin metallic layer in the inner part, a thick cubic phase layer of ZnS, and on this second phase, nanostructures of ZnS hexagonal crystal phase grew up homogeneously. The surface tension, intrinsic to liquids, induces the formation of a microsphere in ZnS sample in order to minimize the surface area. ZnS and SnS hollow semiconducting microstructures have exhibited efficient activity to degrade the methylene blue under simulated sunlight irradiation. The results reveal that ZnS microstructures have higher photoactivity to organic degradation when compare to SnS in the same time interval. The observed results demonstrate the potential of thermal evaporation process without any catalyst material as a simple, fast and efficient route to obtain hollow hierarchically micro/nano architectures of SnS and ZnS with enhanced photocatalytic activity.

“…In addition to examine battery application, we have also performed the photoluminescence and photocatalytic degradation of organic dyes such as methylene blue (MB) and rhodamine B (RhB). There are good reports on SnS nanoparticles which act as better visible light sensitive photocatalyst for photo-degradation of organic dyes [26,[39][40][41] .…”
