“…The predominance of the (0 0 2) plane in all the films clearly shows that the growth of the crystal was such that the c-axis was perpendicular to the surface of the substrate. Our previous work on CdS thin films fabricated at different substrate temperatures showed a similar preferential orientation [22].…”

CdS and Zn-doped CdS (CdS:Zn) thin films have been deposited on glass substrates by spray pyrolysis technique using a perfume atomizer. The influence of Zn incorporation on the structural, morphological, optical and electrical properties of the films has been studied. All the films exhibit hexagonal phase with (0 0 2) as preferential orientation. A shift of the (0 0 2) diffraction peak towards higher diffraction angle is observed with increased Zn doping. The optical studies confirmed that the transparency increases as Zn doping level increases and the film coated with 2 at.% Zn doping has the maximum transmittance of about 90 %. The sheet resistance (R sh ) decreases as the Zn-doping level increases and a minimum value of 1.113 × 10 3 Ω/sq is obtained for the film coated with 8 at.% Zn dopant. The CdS film coated with 8 at.% Zn dopant has the best structural, morphological and electrical properties.

“…A significant variation in crystallite size for the film deposited at 400 °C may be the reason for decreased band gap. The observed E g values are consistent with the reported value of CdS thin films prepared by spray pyrolysis technique [16] .…”

“…The films were excited at the wavelength of 280 nm. PL bands appearing in the energy range of 2.18-2.54 eV are called green bands; bands appearing between 2.07 and 2.18 eV are typically referred to as yellow bands; the orange band is located between 2 and 2.07 eV, and the luminescence observed around 1.54-2 eV is called the infrared / red band [16] .…”

“…The enhanced absorption in the lower wavelength region makes the nano samples a good window layer for solar applications [41]. On the other hand, the low absorption in the VIS-IR regions makes the pure and metal (Cu, Mn) doped In2S3 NPs useful for optical components in high laser window and multispectral applications, providing good imaging characteristics [41] The absorption coefficient was calculated by using the Urbach relation [45].…”

Pure and metal (Cu, Mn) doped In2S3 nanoparticles were prepared by the standard co-precipitation technique. This work aims to study the influence of metal (Cu, Mn) on the synthesized nanoparticles' structural, morphological, optical, photoluminescence, and electrical properties (NPs). The XRD pattern reveals that the metal (Cu, Mn) doped In2S3 NPs were polycrystalline with a cubic phase whose particle size varies between 36.2 and 49 nm. A significant decrease in the crystallite size was observed after metal doping. It is noted from the EDS spectra the elements like In, Cu, Mn and S are present in the NPs. The optical studies reveal that the high transmittance (80%) was observed for pure In2S3 NPs makes them an efficient window layer for solar cell applications. Also, the calculated bandgap energy was found to increase ( 2.8 – 3.28 e V) for metal doping. Photoluminescence measurements reveal that the photoemission is mainly due to the donor-acceptor pair transitions. The electrical studies indicate that the electrical conductivity decreases significantly with doping, and maximum electrical conductivity of 1.28 x 10-6 (Ω m)-1 was obtained for pure In2S3 NPs. A photocatalytic study reveals that high photocatalytic activity is observed for Mn-doped NPs under Methylene blue (84%).
