“…However, this ratio is relatively higher than (S/Zn = 0.96) reported in Ref. [23], where the thin films of ZnS were produced at low pressure by the metal-organic chemical vapor deposition (MOCVD) technique. Furthermore, It is also much higher than the ratio of S/Zn = 0.86, reported by Elidrissi et al [24] who produced ZnS thin films on glass by the spray pyrolysis technique at 773 K. This result shows that the production of ZnS thin film by sol-gel is a very reliable technique for obtaining ZnS thin films without any impurity.…”

Zinc sulfide (ZnS) thin films of different thickness were coated on glass substrates by the sol-gel dip-coating technique. Thickness dependent structural and optical properties of the films were studied in detail. X-ray diffraction (XRD) analysis indicated that the films had mixture of cubic (b) and hexagonal (a) phases with cubic (b) phase being predominant. Scanning electron microscope (SEM) showed that the film surfaces were smooth and crack free. Energy dispersive X-ray (EDX) measurement showed no impurity in the ZnS compound with elemental concentration of Zn/S being 50.38/49.62. Optical measurements showed that optical transmittance of the films were decreased in the visible range as the film thickness increased and band gap of the thin films were estimated to be about 3.61, 3.56, and 3.39 eV for the films with thickness of 100, 220, and 360 nm, respectively. Reactive indices and extinction coefficients of the films were measured by Spectroscopic Ellipsometer. Both the refractive index (n) and extinction coefficient (k) of the films were increased as the film thickness decreased. Electrical measurements showed that the resistivity of the films were decreased as the substrate temperature and film thickness increased.

“…Zinc blende ZnS is stable at low temperature while wurtzite ZnS is stable at high temperature. Zinc sulfide has found use in a variety of applications ranging from electronic devices (2,3) to biology (4,5), such as blue light-emitting diodes (6) and laser diodes (7,8), electroluminescent thin films for displays (9), solar cells (10), and antireflection coatings. Due to quantum confinement effects (11,12), semiconductor nanoparticles exhibit size-dependent optical and electronic properties (13).…”

Zinc sulfide is a II-VI semiconductor with a direct band gap in the near-UV region. Here, we demonstrate the preparation of ZnS nanoparticles (NPs) by spray pyrolysis using zinc diethyldithiocarbamate as a single-source precursor. Solutions of this precursor in toluene are dispersed into fine droplets by an atomizer, and then carried into a tube furnace where they evaporate fully. ZnS NPs then nucleate from the vapor phase. The NPs were characterized by transmission electron microscopy (TEM), highresolution TEM (HRTEM), and optical spectroscopies. The NPs are about 3 -20 nm in diameter and are crystalline, as indicated by the presence of lattice fringes in HRTEM, and by selective-area electron diffraction. Their XRD pattern shows a single peak, indexed to the (111) plane of the cubic zinc blende lattice. The UV absorption spectrum shows peaks in the range of 330-380 nm, and the NP's exhibit bright blue photoluminescent emission under UV illumination.
