Thermoluminescent System for Low Temperatures.

摘要

A system for measurements of the thermoluminescent glow curve, the thermoluminescent emission spectrum and the optical absorption spectrum of solid samples, from liquid nitrogen temperature up to 473 K, is reported. A specially designed temperature programmer provides a linear heating of the sample at a wide range of selectable heating rates, as also long term steady-state temperatures for annealing and isothermal decay studies. The system operates at a pressure of 1.33 x 10/sup -3/Pa. Presently it is being used for lithium fluoride low temperature thermoluminescent studies. (Atomindex citation 20:017542)
