What is ruthenium?


Ruthenium is a kind of hard and brittle light gray polyvalent rare metal element, is a member of platinum group metal. In the crust is only one billionth of the amount, is one of the most rare metal, but ruthenium is indeed the most expensive platinum group metal, although platinum, palladium and other metals are richer than ruthenium. Ruthenium is very stable, corrosion resistance is strong, at room temperature that can be hydrochloric acid, sulfuric acid, nitric acid and aqua regia corrosion.

History of OLED development

Image
With the development of high-tech, we have been in life can often see the shadow of OLED, and many people may know the existence of OLED, but the origin of OLED may be a lot of people do not know. Now, Xiaobian to give you universal about the history of the development of OLED. In 1947, Hong Kong-born Chinese professor Deng Qingyun found in the laboratory organic light-emitting diode, which is OLED, which started the study of OLED, in 1987, Professor Deng Qingyun and Van Slyke using ultra-thin film Technology, using transparent conductive film as anode, Alq3 as light-emitting layer, triarylamine as hole transport layer, Mg / Ag alloy as cathode, made of double-layer organic electroluminescent device. In 1990, Burroughes et al. Discovered OLEDs with conjugated polymer PPV as a light-emitting layer, and the upsurge of OLED research has been around the world. Professor Deng is also known as "the father of OLED". OLED in the two major technical system, low molecular

The basic properties of anthracene

Image
Physical properties white flake crystals with light blue fluorescence or light yellow needles. (Pure white with purple fluorescence) The relative density of 1.25 (27 ℃), 1.283 (25 ℃), the melting point of 217, the boiling point of 342, the flash point of 196.1,121.1 (closed) (above are ℃), steam pressure 0.13kPa / 145 ℃ Insoluble in water, insoluble in ethanol and ether, more soluble in hot benzene. Stability stable Uses Used as a luminescent material (as in a scintillation counter), especially for coatings (eg for absorbing ultraviolet light). Used in the manufacture of anthraquinone and dyes. Also used as pesticides, fungicides, gasoline and other coagulant. Preparation or source  obtained in the final stage of the distillation of coal tar, which can be separated from the anthracene oil portion of the coal tar. Hazard Marking 20 (Corrosive) Derivatives anthralin anthraquinone

The new marke OLED lighting is coming

Image
After 2016 years of rapid development, OLED horn has been fully sounded. Some time ago, Apple Google "looting" OLED, by virtue of their own advantages, OLED in the display area all the way popular. The current market demand for OLED is very strong, OLED screen by virtue of the advantages of self-luminous and flexible, in addition to the traditional mobile phone, TV, VR equipment, can wear intelligent equipment and car display, lighting and so on, many Domain product upgrades and development need OLED support. In the field of lighting, modern home lighting products will benefit from OLED technology. Not long ago the opening of the Taiwan International Lighting Technology Exhibition, Taiwan Industrial Research Institute to build the three major lighting theme pavilion, which " OLED lighting theme museum" in the Taiwan Ministry of Economic Technology to support the "wisdom of life home lighting" as the theme. One of the flexible design will be OLE
