Generalization across samples from different manufacturers and processes is currently under investigation.Luminescent evaluation of five samples produced by Cheetham &amp; Co. gave useful intensities for all emission bands (590 nm, 420 nm and 360 nm TL and blue stimulated OSL), with the spectral and intensity balance of emissions generally similar for each sample. 590 nm emission sensitization was noted after preheating samples to 135°C and 300°C for five minutes.
