Abstract
In the present paper we studied the TL emission of CaF2 doped with Al3+ and La3+ in the nominal concentration range from 0.01 to I mol %. The sample doped with Al3+ showed the best sensitivity to gamma-rays while the pure sample displayed the best sensitivity to UV and visible light. The TL signal of the Al3+ doped sample has a maximum intensity for a nominal concentration of 0.2 mol% of the dopant while in the La3+ sample, the TL emission increases with the concentration of the dopant. The tridimensional TL plot revealed that the emission at 480 nn, observed in all samples, can be due to a luminescence center of intrinsic origin while the emission at 570 nm of the Al3+ doped sample is due to a transition of the Al3+ ion.
