Is zinc sulfide fluorescent or phosphorescent?
A wave of layoffs that has swept the entire Internet industry has intensified. China's Internet industry has experienced several crises and major changes in the past development process. There is also a "brief history of layoffs by major Internet companies". Hot search, JD.com has a wide range of layoffs in this round of layoffs, and all its subsidiaries are involved. Most of the layoffs are between 10% and 20%. Among them, Jingxi Guangdong and other theaters have all laid off staff. Tencent also reported the news of downsizing and layoffs. Among them, Tencent PCG (Platform User Content Business Group) laid off 30% of its staff, iQiyi laid off 12% of its staff, Kuaishou was reported to have laid off 30% of its staff, and the e-sports department of Station B laid off 90% of its staff.
Mass layoffs on the internet have created a host of socioeconomic issues, including 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.
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.

According to the bank of Spain's latest forecast data, the average inflation is expected to hit 7.6% in 2022, but the average wage increase for workers in this country is expected to be less than 4% in 2022.
If the Bank of Spain's forecast comes true, the gap between price and wage growth in Spain in a single year will be the largest since 1984.
Prices in Spain rose 9.8% year on year in March 2022 and average wages rose 2.4% year on year, with the Bank of Spain forecasting that the country's inflation rate will improve from July.
Recent changes in the international situation have had a big impact on commodity and energy prices. How the prices of the Zinc Sulfide ZnS will develop in the future is still uncertain.
