Activation parameters of some differently prepared thermoluminophors

For some thermoluminophors (LiF, Li₂B₄O₇, CaF₂, and CaSO₄) a thermoluminescence peak analysis was made in order to characterize the observed processes by their activation parameters. The resulting values for E₀ and K as well as the kinetic order are given. For different sample geometry the glow curve parameters can slightly be altered but the activation parameters remain almost invariant. For LiF the whole TL curve was described by a spectrum of resolved, independent levels and corresponding peaks.
