Vacuum coated Sb 2 S 3 thin films: Thermal treatment and the evolution of its physical properties

Effect of vacuum annealing on the properties of one step thermally evaporated Sb2S3thin films for photovoltaic applications

“…We found that the preferential orientation of films does not change and the texture coefficient of the (201) plane increased from 4.7 to 6.5 by increasing the annealing temperature from 200 to 250°C. As the obtained values were greater than 1, this means that there are a number of crystal planes oriented in that direction [22] which confirm the enhancement of the crystallinity due to the vacuum annealing treatment. These structural results are crucial in order to improve the performance of the solar cells.…”

“…The spectrum excited these lower laser power, revealed, under ambient pressure, the presence of five well-defined peaks located at 112.6, 189.04, 238.2, 281.6 and 304.7 cm -1 which represent the orthorhombic stibnite phase [21]. The bands observed correspond, according to the Sb2S3 Stibnite phase [22]. In fact, the band presence at 282 and 305 cm 1 confirm the symmetrical C3v vibration modes of the SbS3 pyramidal units which is associated to the Ag mode and to the B1g mode, respectively and both these optical modes correspond to the antisymmetric S-Sb-S stretching vibration and they are due to the orientation of the Sb2S3 polycristalline structure along (310) [23].…”

A novel and fast method to prepare a Cu-supported α-Sb2S3@CuSbS2binder-free electrode for sodium-ion batteries

“…1c. The shis at 146 cm À1 , 192 cm À1 , 239 cm À1 , 279 cm À1 , 299 cm À1 can be assigned to Sb 2 S 3 , 29,30 and the most intense band at 146 cm À1 corresponding to the S-Sb-S bending vibrations, 31 while the two weak peaks at 254 cm À1 and 322 cm À1 correspond to the vibrations of Cu-S bonds and the v 1 symmetric Sb-S stretching vibrations of CuSbS 2 , 32 which implies that a small amount of CuSbS 2 is present in the deposited layer of electrode besides Sb 2 S 3 . The chemical states of elements and composition of as-prepared product were conducted by X-ray photoelectron spectroscopy (XPS).…”

“…2d). It is generally accepted that smaller electrode thickness symbolizes shorter ions and electrons transmission distance, 30 and thus enhances ion and electron diffusion. Additionally, a clear dividing line can be observed between the active substance and the collector, which isn't present in the a-Sb 2 S 3 @CuSbS 2 electrode.…”

SOLVOTHERMAL SYNTHESIS OF Sb2S3 NEEDLES AND STUDY OF THE EFFECT OF THEIR INTERGROWTH ON THEIR OPTICAL PROPERTIES

“…1D nanostructures of Sb 2 S 3 such as nanorods, nanowires, microtubes and nanobelts are common, since the material usually grows anisotropically in the axial direction. Such structures can be obtained by using different synthetic methods: thermal evaporation at high vacuum [3], spray pyrolysis [4], precipitation [5], ionic liquid assisted ultrasonic bath [6], sonochemistry [7 ], colloidal [8], hydrothermal [9,10] and solvothermal [11]. The simplest technique is the hydro-or solvo-thermal synthesis, which additionally it is very powerful for obtaining crystals of good quality with even atypical morphologies.…”
