Thermoluminescence of KCl: Tl Between 30 and 400°C Determined by Simultaneous Intensity and Spectral Distribution Measurements

Origin of the 4750-Å Emission in KCl: Tl Phosphors

“…15 These Tl + concentrations are low enough to cause the presence of all but a negligible quantity of Tl + dimer. 16 Figure 1 shows the emission intensity as a func- tion of the temperature. It can be seen that the emission decreases considerably at low temperatures.…”
