8th new world luminescence dating workshop

(b) Electrons become trapped while holes of missing electrons become localised at particular centres.

It is not intended to be used as a manual but rather as an introductory primer that brings awareness about the principles behind the dating methods, their practical aspects, as well as their applications. Following the introduction in the first section which briefly lays out the historical development of luminescence dating, the second section examines the principles of the dating methods.

(a) Irradiation leads to electrons being expelled from their original site and diffuse within the lattice.

Light (luminescence) is emitted when luminescence centres are encountered by the electrons to give TL or OSL. Examples of TL glow-curves showing (a) natural signal obtained from a mineral sample (quartz) during the first heating and (b) red-hot glow-curve obtained from a second heating (incandescence).
