The TL properties of Li2B4O7:Cu have been studied in single crystal samples grown by the diameter controlled Czochralski method. The TL measurements have been performed using a home-made high sensitivity 3D spectrometer, using a heating rate of 1°C s.-1. Two peaks have been detected in the glow curve, at 145°C and 206°C. The latter proved thermally stable and its TL Intensity linear as a function of absorbed dose, over a wide range. The sensitivity, which was higher than in the powder samples, and the suitable temperature of the glow peak make the crystals very promising for dosimetric use.

Abstract
The TL properties of Li2B4O7:Cu have been studied in single crystal samples grown by the diameter controlled Czochralski method. The TL measurements have been performed using a home-made high sensitivity 3D spectrometer, using a heating rate of 1°C s.-1. Two peaks have been detected in the glow curve, at 145°C and 206°C. The latter proved thermally stable and its TL Intensity linear as a function of absorbed dose, over a wide range. The sensitivity, which was higher than in the powder samples, and the suitable temperature of the glow peak make the crystals very promising for dosimetric use.
