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,...

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...

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...

Rare earth long after glow in the dark powder knowledge

REE-activated alkaline earth aluminate, silicate and other high-tech self-luminous products. Their outstanding characteristics are: a variety of visible light absorption at 10 to 20 minutes, you can continue to light at night in the dark more than 12 hours, the luminous brightness and duration is 30 to 50 times the traditional ZnS glow materials. Glow in the dark powders main technical parameters: 1 initial brightness: glow powder under a certain light brightness (1000LUX), instrumentation brightness value between 0 (typically 3 seconds...

Ultraviolet invisible paint material pigment market prospect is broad

Invisible pigment is a kind of pigment: its characteristic is optical pigment material, light structure color matching principle. There are 18 colors. All the colors are in white shape. Under the irradiation of the purple lamp, all kinds of colors appear immediately and brightly. draw a pattern, day and wall a color, at night in the light, a vivid picture will appear! What is invisible illusory pigment? Invisible illusory pigment is a new high-tech pigment in today's world. It has been applied in some...
