The composite material can emit the blue, green, red, and white fluorescence, such that TIEL can achieve wide-spectrum manipulation by adjusting the component proportions. To sign up for alerts, please log in first. It is also a by-product of the synthesis of ammonia from methane where zinc oxide is used to scavenge hydrogen sulfide impurities in the natural gas: As such, it has found application in luminous paints and as the phosphor in cathode-ray tubes. Chemie. Website © 2020 AIP Publishing LLC. J. T. Randall and M. H. F. Wilkins, Proc. Luminescent materials and phosphor chemistry. (Sax, Dangerous Properties of Industrial Materials) Sulfides of the heavy metals are generally insoluble and hence have little toxic action except through the liberation of hydrogen sulfide. (1) The zinc sulfide, before firing, is a large aggregate of crystallites with the crystal diameter of about 150 Å and contains about 8% of α-form. ZnS:Cu,Al - zinc sulfide co-doped with copper and aluminum - is a green phosphor powder with an emission peak of 530nm. • To prepare a composite CdS-ZnS/zirconium-titaniu m phosphate (ZTP) … Soc. It … Zinc sulfide in a suitably activated form (i.e., with trace quantities of certain elements) can exhibit fluorescence, phosphorescence, and luminescence.

Zinc sulfide is usually produced from waste materials from other applications. Soc. English-Dutch technical dictionary. The first phosphor synthesized was probably an impure barium sulfide preparation with very low luminance efficiency and with the serious shortcoming that it was rather quickly decomposed in moist air, yielding hydrogen sulfide.A more stable sulfide-type phosphor was produced in 1866 by heating zinc oxide in a stream of hydrogen sulfide. There is no cumulative effect from the inhalation of zinc fumes. f. Physik. Typical sources include smelter, slag, and pickle liquors. Figure 2: Silver activated zinc sulfide powder viewed under UV illumination. f. Anorg. Full Record; Other Related Research; Authors: Otomo, Y Publication Date: Sat Aug 01 00:00:00 EDT 1959 Research Org. Roy. Zinc sulfide phosphors are used with radioactive materials, where the phosphor was excited by the alpha- and beta-decaying isotopes, to create luminescent paint for dials of watches and instruments (radium dials).Between 1913 and 1950 radium-228 and radium-226 were used to activate a phosphor made of silver doped zinc sulfide (ZnS:Ag), which gave a greenish glow. In zinc processing: Other industrial compounds. The product is a cubic ZnS:Cu-phosphor, which emits green light at 530 nm. Search nearly 14 million words and phrases in more than 470 language pairs. zinc sulfide phosphor. The phosphorescence and thermoluminescence of zinc sulfide phosphors are governed by the mechanism of electron trapping in the phosphor crystal lattice. Sodium Pyrosulfite Used for Rubber Coagulant.
