In nature, there are thousands of minerals, among which more than twenty minerals can emit visible light under the stimulation of external energy, which is the luminescence of minerals. For example: fluorite, spodumene, emerald and other rare minerals. In general, the luminous pearl refers to fluorite, luminous stone and so on. It is made of stone containing luminescent rare elements.
These stones are some luminous substances in the earth, which are concentrated in the ore from the initial magma eruption to the later geological movement. When these fluorescent stones are placed under white fluorescent lamps, they will emit beautiful fluorescence, which is obviously weak during the day and strong at night.
Brief introduction of Ye Mingzhu
What is the reason for this luminous phenomenon? In recent years, scientific research has studied this luminescence phenomenon. The night pearl is mostly composed of fluorite minerals, and its luminescence is caused by the related electron movement in minerals.
When the electrons in minerals are stimulated by external energy, they change from low-energy state to high-energy state, and when the external energy stimulation stops, the electrons change from high-energy state to low-energy state, and this process will emit light.
In addition to the luminous pearl that needs external energy to stimulate, there are some radioactive isotopes that can self-excite and emit light without any external energy, and the radioactivity of such isotope substances that can self-emit light usually causes harm to human body. In this way, when people encounter unknown luminescent substances, they should try to stay away from them and contact relevant departments for treatment.
