On the Calculation of Activation Energies and Frequency Factors from Glow Curves
TL;DR: In this article, a new method for calculating activation energies and frequency factors from thermoluminescence and thermally stimulated current peaks is described, which uses the total half width ω=T2−T1, where T1 and T2 are the half-intensity temperatures on the low and high-temperature side of the peak, respectively.

Kinetics of cerium emission in a YAG:Ce single crystal: the role of traps
TL;DR: In this article, the authors measured the emission spectra and decay kinetics of a Ce-doped YAG under both optical and gamma excitation, at temperatures ranging from 60 to 600 K.
Journal ArticleDOI
The cracking of Czochralski-grown crystals
TL;DR: In this article, the authors examined the thermal strains existing in crystals during and after pulling and the strains which can be built-in by the facet effect, and they showed that during the growth of a crystal with a radius R, there is a maximum acceptable axial gradient roughly proportional to R−1.5 and that to prevent cracking after growth, there was a maximum rate of cooling proportional to r−2.
