The gamma-ray induced thermoluminescence of specimens of majolica pottery of known origin, and of specimens of majolica of unknown origin collected in the Caribbean area was analyzed to determine if thermoluminescence could be used as an indicator of the provenience of pottery found in an archaeological context. The results of the measurements show that the shape of the gamma-ray induced thermoluminescence glow-curve of the clay matrix of majolica is specific to the geographic locality where the pottery was made, and that the provenience of specimens found archaeologically can be determined on the basis of their thermoluminescence glow-curves, when the curves obtained from the samples with known origins are used as references.

Contrast Exposure

Gamma-ray-induced surface defects in YBa2Cu3Ox (x ≈ 7) have been investigated by thermally stimulated luminescence (TSL) following storage of the samples in dry (vacuum), oxygen, and 98% relative humidity environments. Irradiation of samples stored in either vacuum or oxygen environments shows that no insulating chemical species are formed on the surface of the superconductor. In contrast, exposure to the humid environment produces various chemical components on the surface, and, consequently, enhances the TSL yield. Comparison of the YBa2Cu3Ox, TSL glow curve and emission spectra with those of BaCO3 suggests that one of the components contributing to the purported YBa2Cu3Ox luminescence is BaCO3. Evidence for formation of other chemical species and the suitability of the TSL technique for their determination are discussed.

Thermoluminescence Glow Curve

The shape of a thermoluminescence (TL) glow curve has fundamental importance for calculating the characteristic parameters of trap levels within the band gap. TL analysis are mostly based on the three-parameter general order kinetics model. The parameters are activation energy, order of kinetics, and frequency factor. Peak shape method is one of the most prominent methods for extracting the activation energy from a TL curve. An overview of different peak shape methods along with an alternative approach formulated directly from basic TL equations is presented in this chapter. Generally, peak shape method requires prior knowledge of order of kinetics to determine activation energy which creates a difficulty due to the non-uniqueness of symmetry factor for a particular value of order of kinetics. A modified version of peak shape method which is free from this constraint is discussed here. Activation energies from experimental curves of tremolite and actinolite are estimated using peak shape method. Limitation of peak shape method for saturated TL peaks with heavy retrapping is also discussed.
