Resumen

The behaviour of afterglow (AG), thermoluminescence (TL) and infrared-stimulated luminescence (IRSL) in beta-irradiated chemical vapour deposition diamond is presented. The TL glow curve consists of four peaks with maxima at about 380, 430, 530 and 610 K. TheAGdecay is fitted by Becquerel's lawwith exponent close to 1, and correlates well with the thermal emptying of the traps responsible for the 380K peak. Stimulation with IR light (830 nm) creates intense IRSL and destroys the 380, 430 and 530K peaks. Illumination with shorter wavelength light also destroys the 610K peak. The thermal cleaning procedure removes subsequently TL peaks, AG and IRSL. The AG signal decays together with the disappearance of the 380K peak. The IRSL signal decays continuously with the removal of the 380, 430 and 530K peaks. Traps responsible for the 610K peak do not participate in the IRSL process. © 2009 WILEY-VCH Verlag GmbH & Co.
