American Elements manufactures ZnS:Cu,Al Phosphor in both research and bulk quantities. Educ. NL:zinc sulfide phosphor. 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. A phosphor is composed of a base compound (a pure insulating material or a wide energy gap semiconductor, as in the case of ZnS) that is “activated” with the addition of a small percentage of impurities (doping). zinc sulfide phosphors phosphor infrared Prior art date 1956-04-30 Legal status (The legal status is an assumption and is not a legal conclusion. EFFECT OF NEUTRON BOMBARDMENT ON A ZINC SULFIDE PHOSPHOR. By adding other metals, phosphorescence in other regions of visible light can be obtained. ZnS:Cu,Al - zinc sulfide co-doped with copper and aluminum - is a green phosphor powder with an emission peak of 530nm. Lithopone, which is a mixture of zinc sulfide and… 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. These impurities deform the crystal structure, producing various types of metastable energy levels between the conduction band … Expired - Lifetime Application number US581370A Inventor Herman C Froelich 1.Luminous powder with automatic absorption of light, store light, luminous performance, absorb all kinds of natural light (sunlight), lighting, etc. The phosphorescence and thermoluminescence of zinc sulfide phosphors are governed by the mechanism of electron trapping in the phosphor crystal lattice.

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 the image aside (Massimiliano Malgieri et al 2018 Phys. yellow green glow in the dark Zinc Sulfide phosphor powder . When pure zinc sulfide is struck by an electron beam, it gives off a greenish glow. There is no cumulative effect from the inhalation of zinc fumes. 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). sodium pyrosulphite, 97% min purity, white crytalline powder, industry grade, smbs manufacturer, rubber solidifying agents.
