The main applications of rare earth luminescent materials

The use of rare-earth light-emitting materials will bring the effects of environmental protection and energy saving, good color rendering function and long life number to the light source, which is conducive to promoting the upgrading of products in the current significant area. Therefore, once the rare-earth light-emitting materials are created, they are quickly used in the production of color television picture tubes (CRTs) and fluorescent lamps. The industrial use of rare-earth light-emitting materials in China also began in the [...]

Types of electroluminescent planar display screens

This type of product is based on the principle of inorganic powder electroluminescence (EL) technology, which is characterized by planar luminescence, and can realize color dynamic pattern and text display through the circuit. Existing products include: ultra-thin flexible plastic EL, flat glass EL, enamel EL, long life outdoor plastic EL. The basic technical indicators are as follows: 1) indoor plastic EL screen: maximum size: 80cmX60cm; thickness: 0.2-0.5mm; brightness: 5-120cd /m2; Use conditions: 80-110v, 400-800hz or 220V,50Hz, PET plastic sheet as raw [...]

The difference between luminescence, fluorescence and reflection

When the setting sun fades away, when the night falls and the lights come on, I suddenly find that the city at night is so beautiful that compared with the day, it seems to have a soft, romantic charm. As the finishing touch pen, of course, is the light, a variety of, colorful light. Light is different, too. There are spontaneous light, luminescence is a non-thermal emission of materials, the main application field is in the light source, display devices, [...]

What is the principle of chemiluminescence

Chemiluminescence is a common natural phenomenon, the use of chemiluminescence determination of chemiluminescence reaction reactants, catalysts, sensitizers, inhibitors, coupling reaction reactants, catalysts, sensitizers method is called chemiluminescence method. So, what is the principle of chemiluminescence? Below small make up to introduce the principle of chemiluminescence. In order for a chemical reaction to produce chemiluminescence, the following conditions must be met: first, the reaction must provide sufficient excitation energy, which is provided by a single step, since the energy released in [...]

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 [...]
