Fiberhyphen;optichyphen;coupled, laser heated thermoluminescence dosimeter for remote radiation sensing

摘要

We describe an optically transparent, laser heated, thermoluminescent glass dosimeter that is used for fiberhyphen;optichyphen;coupled remote radiation monitoring. The glass consists of ZnS nanocrystallites embedded in a Vycor glass host, doped with Cu1+and Nd3+ions. An 807 nm, 1 W GaAlAs laser is used to rapidly heat microscopic regions, surrounding the Nd3+ions, in the composite glass to stimulate bluehyphen;green thermoluminescence from metastable traps populated by exposure to ultraviolet or60Co ggr; radiation.
