What is a tattoo, we have already mentioned in related articles, so the next thing I will talk about is luminous tattoos. In fact, this is the first time I have heard of this term. Luminous tattoos are tattoos that can last for several hours, just like glow sticks, they will emit long-lasting fluorescence after absorbing light.
The luminous component of the night light in the early days was radium, but it was too harmful to human body, and it was forbidden now. Now it is mainly long-lasting rare earth thermoluminescent luminescent materials, such as luminescent powders such as lanthanum oxide and praseodymium oxide. After these materials are implanted in human skin, they will have a continuous light after absorbing light. In principle, the tattoo must be a material that cannot harm the human body.
