As a chemical product, many people do not know much about luminous powder. Many people will ask the question, “Is glow in the dark powder a necessity of life?” This question is actually very acute. In daily life, it is really not a necessity, but sometimes it is really. Here we can let everyone know through a case.
During the 9/11 terrorist attack in the United States, when the disaster suddenly came, the World Trade Center could be said to be in a state of a power outage. Ordinary safety signs did not work, and the survivors who had escaped more than 18,000 had followed the night light Signpost made of powder, escaped from the World Trade Center. So when it comes to luminous powder, we hope that it is not a necessity for a lifetime, but it is already there when we need it, so it is best.
The glow effect of luminous powder can be said to be very magical, so how does it emit light? Is it the same as the light stick used in the concert? In fact, the luminous powder absorbs the energy of light and stores the energy under the light. When the light is weak or no light, the luminous powder will release the stored energy. For a reason, this product can be understood as a light-filled cup that can emit light without electricity.
But the lightstick is not. The light stick is the material inside which reacts and emits light, and it is a one-time light, and it cannot be reused. The luminous powder stores light first when there is light, and releases the light it stores when there is no light, and the cycle repeats.
There is also a material that many people mistake for luminous powder, which is fluorescent powder. Although the phosphor can emit light in the dark, it needs conditions. The phosphor only emits light under the ultraviolet light. When the ultraviolet light irradiates it, it emits light. It will not emit light without irradiation. The noctilucent powder can absorb light under both ultraviolet and normal light. The irradiated light stops, and it continues to brighten. This is the biggest difference between fluorescent powder and noctilucent powder.
In general, as a luminous chemical material, the luminous powder is used in a very wide range. In a dark environment, the light emitted by the luminous powder can be said to be a pointer, bringing people safety. Still, luminous powder, we hope that our life is not a necessity of life, but it is already there when we need it, so it is best.
