The characteristics of thin film electroluminescent displays produced using sol–gel produced tantalum pentoxide and zinc sulfide

Synthesis of nanometer-size Bi3TaO7 and its visible-light photocatalytic activity for the degradation of a 4BS dye

“…No characteristic peaks of the 4BS dye appear in the spectrum of the recovered Bi 3 TaO 7 catalyst. The broad bands between 450-1000 cm À1 in the two spectra are mainly assignable to Bi-O, Ta-O-Ta and Ta-O stretching vibrations [42,43] and the bands at about 3430 and 1630 cm À1 can be ascribed to water molecules adsorbed on the surface of the catalysts. There are however, some slight differences between the two spectra.…”

Influence of deposition time on ZnS thin film growth over SiO2 and glass substrates

“…It is used as a key material for light-emitting diodes [2], cathode-ray tubes [3], thin film electroluminescence [4], and window layers in photovoltaic cells [5]. The ZnS thin film is these excellent optical characteristics like high refractive index and high transmittance find it is application in thin film solar cells (TFSCs) as a buffer layer [6].…”

Substrate dependent structural, optical and electrical properties of ZnS thin films grown by RF sputtering

“…Zinc sulphide (ZnS) is a II-VI compound semiconductor material which has great importance in light emitting diodes [1], cathode-ray tubes [2], thin film electroluminescence [3] and window layers in photovoltaic cells [4] due to its large bandgap of 3.7 eV [5]. It is potentially important material to be used as an antireflection coating, detection emission, and modulation of visible and near UV light.…”
