Zinc sulfide in a suitably activated form (i.e., with trace quantities of certain elements) can exhibit fluorescence, phosphorescence, and luminescence. ZnS:Cu,Al - zinc sulfide co-doped with copper and aluminum - is a green phosphor powder with an emission peak of 530nm. 979 zinc sulfide price products are offered for sale by suppliers on Alibaba.com, of which sulfide accounts for 9%, pharmaceutical intermediates accounts for 1%. Typical sources include smelter, slag, and pickle liquors. 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. ZnS:Ag PHOSPHOR POWDER EJ-600 . In the presence of a relatively high percentage of lead or certain other agents and after the usual excitation, zinc sulfide phosphors become capable of storing luminescence energy at such a high potential that, unlike phosphorescence, it can be released only by radiation with the near infra-red. zinksulfidefosfor.

The exact color given off by a phosphor also depends on the presence of small amounts of impurities. The long afterglow phosphors can absorb the green TIEL from ZnS:Cu and then convert it into blue and red photoluminescence (PL) through photostimulated luminescence (PSL). Soc. (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. 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. Roy. Full Record; Other Related Research; Authors: Otomo, Y Publication Date: Sat Aug 01 00:00:00 EDT 1959 Research Org. The phosphorescence and thermoluminescence of zinc sulfide phosphors are governed by the mechanism of electron trapping in the phosphor crystal lattice. zinc sulfide phosphor. (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. ON THE CRYSTAL GROWTH OF ZINC SULFIDE PHOSPHOR.
