A variant of the isothermal decay method to determine the trap activation energy E inthermoluminescence is put forward. The area under the phosphorescence curve recorded at different temperatures is employed to calculate E by re-arranging the original equations by Randall–Wilkins, Garlick–Gibson and May–Partridge. As an example, the proposed method is applied to calculate E for a real phosphor and compared with other well-established methods.
