Instructions for the use of long-acting luminous powder, technical indicators
Long-term luminous powder soil type belong to alkaline earth aluminate long afterglow luminescence materials, components can be expressed as: Al2O3 · (Sr, Mg, Ca) O: (Eu, La, Dy) B, can be in the sun or light absorbance 5-20 minutes later, will absorb the light energy stored in the crystal lattice, after can convert the energy into light energy in the dark and light, which can effectively sustained glow (luminescence brightness is more than 10 MCD/m2) to 8 to 10...
