Luminous paint matrix

Luminous paint matrix , activator and coactivator ( also known sensitizer ) rational choice is its excellent performance afterglow important guarantee . Necessary to provide a suitable matrix crystal environment required the activator ions are those having a relatively low energy of 4f → 5d transition of rare earth ions , and photoluminescent paint are not equivalent auxiliary activation substituted divalent alkaline earth metal ions in the formation of different depths trap for storing electrons or holes [ 3 ] . When a light beam is incident to the solid material, the luminescence centers exist between different types of sub-layer interlacing the electronic level will be in the base of the ionic state and excited state transitions between the movement , the photoluminescent stones beam will be transferred at this time to the excited electrons , that is, the wavelength of the light is absorbed. However, in the excited state is a metastable electronic , once light stop , the electrons release the energy of the light wavelength that transitions to the ground state , thereby causing the light-emitting substance , which is a light energy storage process .
