“…[1][2]. CdS thin films have been deposited by various methods such as thermal evaporation [3], sputtering [4], spray pyrolysis [5], electro deposition [6], chemical bath deposition [7], SILAR method [8] and pulsed laser deposition [9]. The spray pyrolysis technique is more advantageous when compared with other methods.…”

Cadmium Sulphide (CdS) thin films have been coated on glass substrate at 400°C by spray pyrolysis (SP) technique using different precursor concentration (0.025M, 0.05M,0.1M,0.15M and 0.2M). CdS thin films were characterized by various techniques such as X-ray diffraction, SEM and optical studies. X-ray diffraction measurements show that CdS thin films belong to the cubic crystal structure with preferential orientation along (1 1 1) direction. The surface morphology of the thin films was analysed by scanning electron microscopy (SEM). The optical energy band gap of thin films is between 2.43 -2.16 eV. The luminescence spectrum shows a strong green emission peak at 518 nm for 0.025M, 519 nm for 0.05M, 521 nm for 0.1M, 525 nm for 0.15M and 517 nm for 0.2M.

CdS nano-particulate films were prepared at the air/water interface under Langmuir monolayers of arachidic acid (AA) via interfacial reaction between Cd 2+ ions in the subphase and H2S molecules in the gaseous phase. The films were made up of fine CdS nanoparticles with hexagonal Wurtzite crystal structure after reaction. It was revealed that the formation of CdS nano-particulate films depends largely on the experimental conditions. When the films were ripened at room temperature or an increased temperature (60 o C) for one day, numerous holes were appeared due to the dissolution of smaller nanoparticles and the growth of bigger nanoparticles with an improved crystallinity. When the films were ripened further, CdS rodlike nanoparticles with cubic zinc blende crystal structure appeared due to the re-nucleation and growth of CdS nanoparticles at the stacking faults and defect structures of the hexagonal CdS grains. These structures were characterized by transmission electron microscopy (TEM), high-resolution TEM (HRTEM), and X-ray diffraction (XRD). These results declare that CdS semiconductor nanoparticles formed at the air/water interface change their morphologies and crystal structures during the ripening process due to dissolution and recrystallization of the particles.

“…Numerous methods have been developed for the preparation of CdS nanocrystalline films like chemical vapor deposition [13], vacuum deposition [14], electro deposition [15,16], spray pyrolysis [17,18], chemical bath deposition [19,20], micelle method [21], or hybrid electrochemical/chemical synthesis [22]. Among them, chemical bath deposition (CBD) is one the most promising techniques for film synthesis since it allows for a continuous coverage of rough surfaces with a minimum thickness and at low costs.…”
