What is the principle that phosphor gives off light ?

One, “phosphors” luminous enlightenment In order to find out the chemical composition of phosphor powder, we first thought about the luminescence of fireflies. The luminescence principle of fireflies mainly has the following series of processes. Photoforming protein + photoforming enzyme containing oxygenated photoforming protein (emitting green light) Oxygen-containing photogenic protein +H2O photogenic protein That’s why fireflies glow continuously, with flashes of light. It’s worth noting that the green light emitted by fireflies is a “cold light” with a conversion rate of 97%. Secondly, we [...]

Luminous Printing Ink Mixing Method and Direction for Use

These are the guidelines to making photoluminescent printing ink. Your application may require some adjustments to the technical material below. Mix the photoluminescent pigment into clear vehicles. Any other pigment in the medium will obscure the luminosity. Such photoluminescent printing ink is suitable for many surfaces such as paper, textile, wood, plastic, metal, ceramic, etc. The PL printing ink comprises PL pigment, organic resin, organic solvent and solvent assistant. How to make photoluminescent printing ink: 1. The choice of resin. (1)Apply [...]

About photoluminescent inkjet paper

The ideal superior photo quality glossy paper for digital photos and color print-outs Most suitable for high-resolution printers. Photo quality printing in dazzling and strongly contrasting. Excellent ink absorption, quick drying, perfect reproduction of small characters, more real and clear. Photo quality printing in dazzling and glowing in the dark. Directions for use Do not touch the printable side of paper. Moisture and oil from your skin can affect print quality. Hold paper by the edges. Only suitable for ink jet printers. Unavailable for laser [...]

Phosphorescent Injection Molding Recommendations

Avoid exposing product to strong acids and or heavy metal compounds as they will react with the glow component and destroy the phosphorescent effect. Keep Moisture content of product to a minimum. Moisture content should be no greater than 00.05 – 0.10%. Minimum Drying time should be 2- 4 hours at 180℉(Fahrenheit) in either a dehumidifier or hopper dryer. It is recommended that a dew point of -20℉(Fahrenheit)   be achieved for the inlet air Phosphorescent master batches or compound material [...]

Several rare earth elements were discovered successively after 1787, but the corresponding mineral discoveries were few. Due to the limitations of science and technology [...]

Experiment of preparing long afterglow materials by combustion method

Experiment part: Objective: Learn to use the combustion method to rapidly grow the afterglow materials. Understand long afterglow material and its long afterglow principle. Learn to rapidly synthesize inorganic oxides and nanomaterials by combustion method. The synthesis method of long afterglow materials and the related steps of combustion synthesis experiment Experiment principle: Combustion is also called self – propagating high – temperature synthesis. It is a kind of chemical system with high exothermic heat induced local chemical ignition through external energy, forming frontier combustion wave, making [...]

Contrast of zinc sulfide and strontium aluminate phosphor luminescent powder

What is traditional Zinc Sulphide pigment? Some of the first phosphors to be developed were inorganic zinc sulphide compounds. (German submarine commanders during World War I reportedly rubbed these compounds on their hands to read documents during blackout conditions.) These phosphors typically absorb energy from deep blue and ultraviolet light and emit it as yellow-green light.This is useful in that the peak spectral distribution of the emitted light roughly coincides with the peak spectral sensitivity of the human visual system [...]

Photoluminescent Pigment Production Technic Process

( Information for reference ) Phosphor is a special crystal structure luminescent material, which has a strong absorbance – STORING – luminous ability, when illuminated by natural light and the light, that part of the light energy is absorbed and stored, and then in the form of visible light in the dark Slowly release the luminescent material after five minutes after the light in the dark can automatically light for more than 12 hours of light absorption process can be [...]

How to distinguish luminous powder and fluorescent powder?

Luminous and phosphor are the two products, but many people think that is luminous phosphors and think they are following the same substance, small to give you how to distinguish luminous powder and phosphor.: 1 luminous powder: Yes absorbance – STORING – a self-luminous light emitting material, which is a kind of luminous material can be made visible in the dark, called luminous powder, luminous powder it into long-term, short-acting luminous, radioactive luminous, but they are of a material glowing [...]
