What is luminous powder? What is the luminous principle of luminous powder?

Noctilucent powder is a kind of afterglow powder, which can store energy after exposure to natural light, ultraviolet light and light, and it has luminance, which is a kind of luminescent material. This luminescent material can continue to release stored energy for a period of time in the form of visible light after the irradiation of the light source disappears. Luminous powder can be divided into long - term luminous powder and short - effect luminous powder.

Noctilucent powder mainly has the following characteristics:

1. Long afterglow, absorbing ordinary visible light to reach saturation, and continuously emitting light under no light source;

2. Start with high brightness;

3. Stable performance;

4. Non-toxic and harmless.

Precautions:

1. Increase the proportion by 2% to 6%. The larger the dosage, the greater the brightness and duration.

2. If you want to add pigment, choose carefully so as not to reduce the intensity.
