Structural and optical characteristics of SnS thin film prepared by SILAR

Abstract

SnS thin films were grown on glass substrates by a simple route named successive ion layer adsorption and reaction (SILAR) method. The films were prepared using tin chloride as tin (Sn) source and ammonium sulfide as sulphur (S) source. The structural, optical and morphological study was done using XRD, FESEM, FT-IR and UV-Vis spectrophotometer. XRD measurement confirmed the presence of orthorhombic phase. Particle size estimated from XRD was about 45 nm which fitted well with the FESEM measurement. The value of band gap was about 1.63 eV indicating that SnS can be used as an important material for thin film solar cells. The surface morphology showed a smooth, homogenous film over the substrate. Characteristic stretching vibration mode of SnS was observed in the absorption band of FT-IR spectrum. The electrical activation energy was about 0.306 eV.

2D Ductile Transition Metal Chalcogenides (TMCs): Novel High‐Performance Ag2S Nanosheets for Ultrafast Photonics

“…Although great progress has been made in theoretical and experimental research, the experimental study of the nonlinear optical properties and ultrafast photonics of Ag 2 S has not been touched. Based on the above analysis, it is very meaningful and interesting to prepare Ag 2 S SA with excellent performance and apply it to ultrafast photonics to realize ultrashort pulse 48–54…”

“…Based on the above analysis, it is very meaningful and interesting to prepare Ag 2 S SA with excellent performance and apply it to ultrafast photonics to realize ultrashort pulse. [48][49][50][51][52][53][54] In this work, Ag 2 S powders are prepared by hydrothermal method and Ag 2 S nanosheets are prepared by liquid-phase exfoliation method. We characterize the surface morphology, crystallinity, size, thickness, lattice fringes, optical properties, purity, stability, bandgap, and binding energy of Ag 2 S nanosheets by some instrumental measurements.…”

SnS Nanosheets for 105th Harmonic Soliton Molecule Generation

“…For example, the absorption coefficient of SnS nanosheets can be up to ≈10 4 cm −1 and the photoelectric conversion efficiency can be up to 24%, which indicates that SnS nanosheets are very suitable for use as light absorption layer in solar cells. In addition, it has been widely used in water decomposition photocatalysts, photodetectors, gas sensors, biosensors, field effect transistors, thermoelectric devices, electrochemical capacitors, supercapacitors, high‐performance anode materials in lithium‐ion batteries, and sensitive photodetectors . More fascinating is that SnS is nontoxic, rich in earth resources, environmentally friendly, low‐cost, and has other excellent characteristics, so it is of great significance to further explore SnS nanosheets .…”

Synthesis and Optical Characterization of Silver Nanoparticles (Ag-NPs) Thin Films (TFs) Prepared by Silar Technique

“…Among all of this methods, SILAR is the inexpensive, simplest, possible homogeneous deposition on large and complicated area of substrates, less temperature, easy to handle and low time consuming technique compared to the others (Salunkhe et al, 2009;Su et al, 2012;Mukherjee and Mitra, 2015). SILAR offers a great opportunity and a good numbers of advantages: SILAR does not require high quality target or substrates nor does it require vacuum at any stage, easily controlled rate of the film or nanoparticle deposition and the thickness by changing the deposition cycles, production of films or nanoparticle can be made possible at room temperature on less robust materials.…”
