Luminous products have a good absorption effect on ultraviolet rays. They absorb light in the daytime and emit light in the dark, and so on. During the day, it is placed in the sun or outdoors where there is ultraviolet light, which shines in the dark. The intensity and duration of light are different, the luminous intensity will be different, about 30 minutes after irradiation can be more than a few hours of light. When there is no ultraviolet sunlight at night, it can be put under the light to absorb light, There is no need to deliberately bask in the sun, as long as you touch the light source, you will start to shine in the dark. This kind of fluorite, like a firefly, glows slightly at night, like shattered stars scattered on the earth, dotted, chic and low-key romantic.
