Abstract
Based on the laser writing device developed by our group before, wiping the glow is necessary as a function added on the machine. This article is a theoretical and experimental study of glow wiping start from luminescence theory and infrared ray. The trap depths of ZnS: Cu and SrAl2O4:Eu2+, Dy3+ are figured out according to the TSL(thermos stimulated luminescent ) dynamics, then the accurate IR wavelength to release the trapped electrons in proper depth. We select every single wavelength of energy 1nm by 1nm from near IR and deliver it by crystal fiber. The glow fading curves of ZnS: Cu and SrAl2O4:Eu2+, Dy3+ are figured under IR. The TSL spectrum of ZnS: Cu and SrAl2O4:Eu2+, Dy3+are measured with a thermal luminescence meter. The experiment result of glow wiping has proved the theory. This paper provide a pioneer experiment and theoretical base for further study of IR quenching wavelength about more variety of LLP material.
