About electroluminescent powder

From the perspective of luminescent materials, electroluminescence can be divided into non-electroluminescence and organic electroluminescence. Electroluminescent materials are generally such as semiconductor materials. Organic electroluminescent materials depend on the molecular weight of organic luminescent materials It can be divided into small molecules and macromolecules. Organic dyes or pigments are used as light-emitting materials for small-molecule OLED materials, and conjugated or non-conjugated polymers (polymers) are used as light-emitting materials for polymer materials. PPV and its derivatives are typical high-molecular light-emitting materials. Organic [...]

Why wear a reflective vest

Reflective clothing is also a very common kind of clothing in today’s outdoor life. Due to the rapid development of traffic roads, it is easy to cause damage to outdoor work and traveling people. Moreover, we must know that the reason for the large traffic accidents in urban areas in the country is that the drivers do not have a good concentration of attention and do not have a good warning function. Wearing reflective clothing can play a role [...]

What is acrylic ( plexiglass ) glow in dark board

Luminous plexiglass is also a kind of fluorescent plexiglass, which is prepared by mixing luminescent powder and plexiglass. Why is this plexiglass emitting light all night? The so-called luminous board is also classified as plexiglass in the classification, and it is mixed with luminous powder in the production process of plexiglass, and it is named because it can emit light in the dark. So what kind of plexiglass can achieve luminescence? It turned out that this benefited from the raw materials [...]

Luminous road decorated with glow in dark stones

A new planner inspired by van gogh’s famous painting “starry night”, planned a “luminous bicycle path”, high, low power consumption, long life, fast start, small power, no stroboscopic, not easy to produce visual fatigue and other advantages, LED; Floor tile lamp is a product often used in lighting of night scene in recent years, the surface cover of the lamp body that USES stainless steel plate one body and toughened ground glass is used outdoor square whether to achieve [...]

About Phosphorescent Evacuation

On March 8, 2000, a subway accident took place in Tokyo. Trains derailed, six people were killed and sixty injured. If this accident had taken place in a tunnel instead of an open area, these numbers would certainly have been much higher. It is easy to imagine the panic caused if the accident victims were unable to determine the correct direction to evacuate the scene. In such situations, it would be very helpful if Glow-in-the-dark signs were installed in [...]

Development of security printing technology

Anti-counterfeiting industry is an important industry to support and promote the development of market economy. Counterfeit and shoddy commodities are rampant, and market frauds continue to occur, which has become an important factor restricting the sustained, rapid and healthy development of China’s national economy. Due to counterfeiting, the products of a large number of famous and excellent Chinese enterprises have been impacted to varying degrees, disrupting the normal production order of enterprises and seriously damaging the legitimate rights and [...]

Up-conversion nanoparticles convert infrared light into ultraviolet and visible light

Researchers from the department of bioengineering at the national university of Singapore’s college of engineering have developed a new technology that converts infrared light into ultraviolet and visible light through nanoparticles, paving the way for non-invasive treatments of deep tumors, physicists organization net reported recently. The technology, which is said to inhibit tumor growth and control gene expression, is the world’s first non-invasive photodynamic therapy that USES nanoparticles to treat deep tumors. The paper is published in the journal [...]
