Abstract

We describe an optically transparent, laser heated, thermoluminescent glass dosimeter that is used for fiber‐optic‐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 blue‐green thermoluminescence from metastable traps populated by exposure to ultraviolet or ⁶⁰Co γ radiation.
