Intrinsic superlinear dose dependence of thermoluminescence and optically stimulated luminescence at high excitation dose rates
Superlinear dose dependence of thermoluminescence (TL) and optically stimulated luminescence (OSL) has been reported for many materials. The theoretical explanation has been ascribed to competition of either traps or recombination centers, during the excitation stage or during the read-out phase. There has been an account in the literature on superlinearity of OSL associated with merely one tra...
متن کاملOptically stimulated luminescence in synthetic quartz
Optically stiniulated luminescence (OSL). has been studied in synthetic quartz crystals. which had previously been exposed to Jtor X-irradiations. The main emission hands appeared at 380 and -~440 nm. The excitation spectra of these emission bands were now measured and showed both a maximum at 330nm. This maximum coincides with an excitation maximum of the phototransferred thermoluminescence (P...
متن کاملAdvantages and Disadvantages in the Utilisation of Thermoluminescence (tl) and Optically Stimulated Luminescence (osl) for Radiation Dosimetry
Thermoluminescence is an established method for radiation dosimetry as well as retrospective dosimetry. In spite of its great success, different difficulties are associated with its application. These include anomalous fading, changes in the properties of the sample due to its heating in the readout phase, including a sensitization due to the combined effect of irradiation and heating and non-l...
متن کاملOptically stimulated luminescence (OSL) of carbon-doped aluminum oxide (Al2O3:C) for film dosimetry in radiotherapy.
INTRODUCTION AND PURPOSE Conventional x-ray films and radiochromic films have inherent challenges for high precision radiotherapy dosimetry. Here we have investigated basic characteristics of optically stimulated luminescence (OSL) of irradiated films containing carbon-doped aluminum oxide (Al2O3:C) for dosimetry in therapeutic photon and electron beams. MATERIALS AND METHODS The OSL films co...
متن کاملProgress towards robotic in-situ dating of martian sediments using optically stimulated luminescence
Recent exploratory efforts to reveal the evolution and the climatic history of Mars have shown that the planet is still active. The surface of Mars has been, and continues to be, shaped by fluvial, eolian and glacial processes. The timeframe of these events is, however, poorly established. We describe efforts and challenges to adapt optically stimulated luminescence (OSL) dating for robotic in-...
