luminous pigment molecules

Rare earth doped alkaline earth aluminates attenuation mechanism exponential decay with temperature , the lower the temperature , the weaker intensity , temperature, light intensity increases rapidly , the decay time is much shorter.
When the coating is lighting conditions , the part of the light is reflected , another portion of the light into the coating interior. Into the glow gravels emitting pigments are partially absorbed by the pigment in the light-emitting molecules are excited , when these molecules will return to the ground state by radiation in the form luminescence . Therefore, the luminous paint luminous paint luminous performance depends . Rare earth doped glow pigment powders aluminate photoluminescent process can be divided into three main stages: light absorption , energy transfer , the emission of light . Absorption and emission of light occurs in the transition between energy levels , have been excited state . Excited state of motion is the energy transfer process .
