Is the luminous stone man-made? Does it radiate? What are its uses?

What is an artificial luminous stone:
Artificial noctilucent gravel, also known as artificial luminescent gravel, is the use of rare earth elements activated alkaline earth aluminate, silicate, and other high-tech spontaneous light products
Luminous stone Product Introduction:
Chinese name: artificial stone is also called artificial light luminous debris field application: home decoration, garden design using rare earth elements, the company using the new type to grow light illuminated material itself characteristic, combining the latest artificial jade production technology to produce a luminous debris with hardness and appearance characteristics of natural stone material, at the same time without the radioactive harm of natural stone material, the product is widely used in indoor and outdoor decoration, landscape design, and other fields, the novel luminous effect, not only beautify the environment, the ornament and foil landscape, more night indicates the practical function and tags, so was deeply loved by the masses of customers at home and abroad.
Luminous stone features:
After absorbing all kinds of visible light for 10 ~ 20 minutes in the daytime, it can continue to glow in the dark for more than 12 hours. Its brightness and duration are 30 ~ 50 times that of traditional ZnS luminous materials, and it can be recycled for infinite times. It is non-radioactive and harmless to human body.
Luminous pebbles glowed stone glowed jade
Noctilucent (illuminated) pebbles is to develop a new type of indoor and outdoor decorative materials, with resin or ceramics as a main ingredient in luminescent materials forming after special craft processing, there are natural forming and molding, can be used as other ingredients, after crushing minimum size is fine long hair, it is applicable for road style, artistic concept, channel direction. It is a good material for modern plastic arts and guidance because of its small size.
Luminous stone features:
The excitation storage condition is low and the duration of high brightness is long. High and low temperature resistance, good electrical insulation performance. Good strength, hardness, corrosion resistance and chemical stability; Optical properties, friction reduction, wear resistance and noise reduction. Environmental protection, safety, light quality. Plasticity is strong, modelling change is big, processing is formed easily. The high recycling rate is recognized by the growing awareness of environmental protection.
