Glow in the dark pigment powder

There are many glow in the dark products in the market nowadays, from mobile phone covers to toys. If you have seen any of these products, you know that they all have to be “charged”. You hold them up to a light for a few minutes, and then take them to a dark place where they glow for several hours.

All glow in the dark products contain phosphors. A phosphor is a substance that radiates visible light after being energized. The two places where we most commonly see phosphors are in a TV screen or computer monitor and in fluorescent lights. In a TV screen, an electron beam strikes the phosphor to energize it. In a fluorescent light, ultraviolet light energizes the phosphor. In both cases, what we see is visible light.

Photoluminescent glow in the dark powder is actually called phosphorescent crystals or pigments. This powdery substance absorbs light and then re-emits it over a length of time. This occurs when electrons absorb energy in the presence of light and move up to a higher orbit. In the absence of light energy, these same electrons fall from a higher energy level to a more stable energy level. When this occurs, they emit energy in the form of visible light. No chemical reaction actually occurs.

To make a glow in the dark product, what you want is a phosphor that is energized by normal light and that has a very long persistence. Jolin Corporation’s photoluminescent glow in the dark pigment powder are derived from non-radioactive natural rare earth mineral crystals that possess the unique capacity to absorb and store energy from ambient light. In darkness, the crystals instantly begin to emit a luminous glow by releasing the stored light energy. Natural rare earth mineral crystals are the primary components that energize glow in the dark products. We have been developed based on the latest breakthroughs in photoluminescent technology. They come in a variety of colors and different particle sizes to suit many requirements. They are utilized primarily in safety grade commercial products such as signs and emergency egress guidance systems. They are recognized as the essential ingredient for the satisfactory performance of photoluminescent safety products.

There are many types of phosphors with these properties. These include:

Alkaline Earth Aluminates

Relatively new technology, able to offering the brightest and longest lasting glow in the dark pigment powder, and a spectrum of colors from yellow-green to violet. Sometimes improperly referred to as Strontium Aluminate, Silicate Aluminate, or Alkaline Earth Aluminate. Made from rare-earth crystals, these “earth crystals” can include Strontium, Magnesium, Calcium, and Barium. Silicon and Titanium may also be present. Europium is typically used for doping. Acid will decompose this type of pigment.

Coated Alkaline Earth Aluminate

Pigments are manufactured by coating Alkaline Earth Aluminate pigments with a protective water-proof coat. These glow in the dark pigments  powder are suitable for use in both solvent and water-based mediums. Acid will decompose this type of pigment.

Alkaline Earth Silicate

Fairly new pigment technology that produces a pure blue glow color not available from alkaline earth aluminates. Pigments are not water soluble and are stable in most acids.
