Is zinc sulfide fluorescent or phosphorescent?

Recently, on Sinopec's annual results teleconference, the company representative answered questions about the oil prices, and said that the future trend of oil prices is still very uncertain, and it is expected to be around $100 this year and $85 next year respectively.

Sinopec, "There are many factors affecting oil prices at the moment, including geopolitics, macroeconomic trends, the implementation of the policy of OPEC+, the strength of the US DOLLAR and so on. We see a lot of uncertainty in the future oil prices. It is impossible to predict the accurate price, but a general trend could be estimated."

According to Sinopec, international institutions generally have a forecast of around $100 this year and around $85 next year in the oil prices. As geopolitical problems and other issues ease next year, oil prices will be lower than this year.

The volatile oil prices in the international market will continue to affect lots of industries and the supply of many Zinc Sulfide ZnS.

Overview of Zinc Sulfide ZnS power

Zinc sulfide ZnS is a white to off-white or light yellow powder, which becomes darker when exposed to light, stable in dry air, and gradually oxidized to zinc sulfate when stored for a long time in humid air or containing water. Soluble in dilute inorganic acid, soluble in alkali, insoluble in water. Relative density 3.98 (alpha type), (d25) 4.102 (beta type). irritating.

Is zinc sulfide fluorescent or phosphorescent?

Zinc sulfide ZnS is one of the most common phosphorescent materials. Phosphorescence is a special type of photoluminescence. Unlike fluorescent substances, phosphorescent materials emit absorbed energy immediately.

Zinc sulfide ZnS is white or slightly yellow powder. Turns into crystals when burned in H2S gas. Its α variant is a colorless hexagonal crystal with a density of 3.98g/cm3 and a melting point of 1700°C. Its beta variant is a colorless cubic crystal with a density of 4.102 g/cm3, which transforms to the alpha form at 1020°C. Zinc sulfide ZnS is present in sphalerite. Insoluble in water, soluble in acid. See the daylight dim.

Zinc sulfide ZnS is converted to zinc sulfate in humid air for a long time. It is generally derived from the action of hydrogen sulfide and zinc salt solution. If a small amount of Cu, Mn, and Ag are added to the crystalline ZnS as activators, different colors of fluorescence can be emitted after being illuminated. Zinc sulfide ZnS can be used as analytical reagents and coatings. Can be used to make paints, opaque glass, rubber, plastics and phosphors.

Application of zinc sulfide ZnS power

Zinc sulfide ZnS is often made from scrap and used for other purposes. Typical sources include smelters, slags, and pickling liquors. It is also a by-product of ammonia's methane synthesis, where zinc oxide is used to remove hydrogen sulfide impurities from natural gas.

High-purity crystalline zinc sulfide powder is an important basic material, which is widely used in civil, military, aerospace and other high-tech fields. It is also an extremely important window material for medium and long-wave far-infrared precision guidance and far-infrared imaging, especially in frontier technology fields such as national defense and military. The applications of zinc sulfide are as follows: Luminescent material.

Zinc sulfide ZnS, with a small amount of a suitable activator, is highly phosphorescent and is currently used in a variety of applications from cathode ray tubes to X-ray screens to glow in dark products. When silver is used as the activator, the resulting color is bright blue with a maximum wavelength of 450 nm. The use of manganese produces a red-orange color around 590 nm. Copper glows for a long time and has the deep green glow we are familiar with. Copper-doped zinc sulfide ("ZnS+Cu") is also used in electroluminescent panels. It also exhibits phosphorescence due to impurities in blue or ultraviolet light.

Optical material

Zinc sulfide ZnS is also used as an infrared optical material, which transmits from visible wavelengths to just over 12 microns. It can be used as the plane of an optical window or the shape of a lens. It is made of hydrogen sulfide gas and zinc vapor microchips and is sold as FLIR grade (forward looking infrared), in which zinc sulfide is creamy yellow and opaque. When hot isostatic pressing (HIPed), the material can be transformed into a transparent water form known as Cleartran (trademark), an early commercial form sold as Irtran-2, but this name is now obsolete.

The Zinc Sulfide ZnS industry has experienced demand expectations driven by the rise and the off-season tired stock driven by the seasonal decline in two rounds of the market. Affected by the COVID-19 epidemic and other factors, inventories of manufacturers continue to accumulate, putting pressure on market sentiment. In addition to off-season factors, the weak trend of Zinc Sulfide ZnS also reflects the market's concern about the epidemic and some other related enterprises' financial situation.
