Some studies on preparation and characterisation of cadmium sulphide films

The effect of annealing temperature on the structural, optical, and electrical properties of CdS films

“…The as-deposited and annealed CdS films at low temperature (T < 623 K) exist in two crystalline phases: cubic (C) phase (zinc blende-type, JCPDS 06-0314) and hexagonal (H) phase (wurtize-type, JCPDS 10-0454), in line with the literature. 8,15,16,24,[32][33][34][35] Annealing leads to an overall improvement in the intensity of the peak heights, indicating that increasing annealing temperature increase the crystallinity of the film. By increasing the annealing temperature, the hexagonal phase becomes dominant and finally at T = 823 K the structure becomes 100% hexagonal phase.…”

Chemical bath deposition of CdS films on different substrate orientations

“…It is known that high temperature increases the deposition rate, reducing the time of growth by the higher energy applied. However, recent reports about the growing of CdS films by CBD close to room temperature conditions [17,18] claims that high quality films suitable for solar applications and for nanotechnology can be obtained. By the other hand, vertical position of substrates for CBD-CdS deposition is normally reported, but any explanation about this condition is given [19,20].…”

The thermoluminescence properties of CdS films under nitrogen atmosphere

“…The as-deposited and annealed CdS films (To623 K) show a mixture of cubic (C) phase (zinc blende-type) and hexagonal (H) phase (wurtize-type) at low temperature. It has been reported that chemically deposited CdS films onto the glass substrate are either hexagonal or cubic phase [28,29,32,[42][43][44][45][46]. It is known that there are two possible ways for the deposition of CdS films during CBD process: (i) ''ion-by-ion'' process (heterogeneous reaction) and (ii) ''cluster-by-cluster'' process (homogeneous reaction), which results in pure hexagonal or mixed hexagonal-cubic phase and pure cubic phase, respectively [8,30].…”
