The Photoluminescent Rigid Sheet principle

The material preparation process , the doped luminescent center -forming element in the matrix and the trapping realglow yellow green excited by external light , the light emitting center of the ground state to an excited state , when the electron transition from the excited state when the ground state , a realglow gravel driveway . At the same time , some of the electrons in the excited fall into the trap center is bound to complete the energy reserves. At the same time , some of the electrons in the excited fall into the trap center is bound to complete the energy reserves. After the light is removed, by the ambient temperature perturbation energy electrons out of the trap fell realglow gravels for sales ground state , releasing the shackles in the center of the trap formed excitation-emission light.
