glow in the dark stones is right

Of not emitting substance contained in the relevant saying, but certainly not the composition of the light-emitting jade because jade is actually a crystalline form of aluminum oxide, which is not illuminated.
There are two possible common luminous minerals, one fluorescent substance, one phosphorescent substance. Only when a fluorescent substance is excited (visible light, ultraviolet, or other types of radiation) will light, the excitation source is removed not shine, such as our common fluorescent; glow in the dark stones was removed over a period of time after the excitation source is still light, such as zinc sulfide. Natural substance capable of emitting light often contain radioactive elements, to which fluorescent substance or a glow in the dark stone provides the radiation, so harmful to people. There is the case of a light, that is, the phenomenon of energy release of radioactive material, such as radium and radon, which is a radioactive element itself emits light.

glow in the dark tape quality products

According to Champoux Consulting released the " 2009-2012 China iron oxide pigments market depth research report" shows how, under the current unfavorable situation , iron industry to increase realglow gravel driveway , should do the following three things: First, do not be afraid difficult to meet the challenges to quality products and good service , bigger domestic market, stabilize the foreign markets, emerging markets ; second, the steady adjustment of realglow decorative stone upgrading, change the current market pressures , environmental pressures to accelerate the adjustment , enabling backward the opportunity to seize the enterprise features , implementing multi-species development ; third , continue to promote the development of innovation and further strengthen technological innovation, device innovation, energy conservation, through the device unit , control, intelligence , and promote realglow glow in the dark , low energy consumption and achieve cleaner production, iron oxide pigment industry in innovation , enhance the image in development, stand on a new starting point , and enhance overall competitiveness .

glow in the dark tape surrounding environment

Traditional fluorescent coating materials can be divided into self-luminous and phosphorescent two. Self-luminous fluorescent agents are mostly carried by its own trace of radioactive material realglow pigments in paint ray excited luminescence fluorescent agent . The storage agent is basically fluorescent light does not contain radioactive materials , but requires advance and reserve sufficient strength to absorb external light, the electrons from their high energy level to a lower energy level transitions and stored . When darkness surrounding environment , and then gradually slow release realglow decorative stone absorption of energy from the high energy level at this time electronic transitions to the low-level , fluorescent agents began to glow. Because of photoluminescent material itself does not carry ray excitation , so the degree of temporary inferior afterglow lasting self-luminous .

glow in the dark material in the production

Since the electrons are bound by the trap at ambient temperature disturbance gradually out of the trap , the light-emitting performance of a long process , thereby forming a long afterglow . realglow decorative stone in the production , should choose ; afterglow luminous powder , luminous powder luminous green varieties can be selected ; luminous white luminous yellow green realglow stone gravel and green luminous sky blue luminous . Because there is no other color luminous powder luminous powder brightness over . So try to use caution.
