Time-Resolved Optically Stimulated Luminescence (TR-OSL) from single crystalline YAlO3:Mn2+ samples was investigated using a green light emitting diode (lambda- 525nm) as stimulation light source. The TR-OSL decay curve of the material can be described with a single exponential decay function with a lifetime about 80 ms that does not depend on irradiation dose in the range from 50 mGy to 1 kGy. This OSL decay is superposed on a photoluminescence signal with a much shorter (3.5 ms) decay lifetime. The Mn2+ photoluminescence decay with a lifetime of 3.5 ms can be easily eliminated by corresponding time resolution using pulsed OSL readout. Dose response and thermal stability of the OSL signal are consistent with the previous thermoluminescent (TL) studies of the material.

Time-resolved OSL studies on BeO ceramics Bulur, Enver (Elsevier BV, 2013-12) Time-Resolved Optically Stimulated Luminescence (TR-OSL) from BeO ceramics was investigated using a blue laser (445 nm) as stimulation light source. It was observed that, at relatively low dose levels (up to similar to 25 Gy) the TR-OSL decay curve can be approximated with a single exponential decay function with a lifetime of similar to 26 gs at room temperature. Beyond 25 Gy a new decay component with a lifetime of a similar to 2 ts was observed in addition to the similar to 26 mu s component. Thermal sta...
Optically stimulated luminescence characteristics of BeO nanoparticles synthesized by sol-gel method ALTUNAL, VOLKAN; YEĞİNGİL, ZEHRA; TÜKEN, TUNÇ; Depci, T.; ÖZDEMİR, ALİ CAN; Guckan, V.; Nur, N.; Kurt, K.; Bulur, Enver (2018-11-01) Optically Stimulated Luminescence (OSL) properties of the sol-gel synthesized nano-powders of Beryllium Oxide (BeO) were investigated. Luminescence properties of BeO nanoparticles are dependent on the crystal structure, particle size, and morphology and therefore strongly dependent on the way of synthesis, thus the preparation was modified to enhance the OSL signal from the material. Structural, thermal and morphological properties of BeO in nanopowder and pellet forms were studied using X-Ray Diffraction (...
Optically stimulated luminescence from quartz measured using the linear modulation technique Bulur, Enver; Murray, A.S. (2000-12-15) The optically stimulated luminescence (OSL) from heated natural quartz has been investigated using the linear modulation technique (LMT), in which the excitation light intensity is increased linearly during stimulation. In contrast to conventional stimulation, which usually produces a monotonically decreasing signal, linearly increasing the stimulation power gives peaks in the signal as a function of time. In cases where the OSL signal contains more than one component, the linear increase in power of the st...
Photo-transferred luminescence from BeO ceramics Bulur, Enver (2007-03-01) Temperature and radiation dose dependences of the thermoluminescence, photo-transferred luminescence signals from BeO ceramics were investigated using blue-green stimulation (420-550 nm). Several deep traps that act as sources for the photo-transferred luminescence signals, located in 400-625 degrees C region of the TL glow curve, were distinguished.
PRELIMINARY OSL STUDIES ON BEIGE SEPIOLITES Bulur, Enver (Oxford University Press (OUP), 2008-09-01) Radiation-induced luminescence signals in beige sepiolite samples were investigated using optically stimulated luminescence. A thermally stable, light-sensitive radiation-induced signal was detected, and radiation dose response and thermal properties of this signal were studied. The thermal stability and dose sensitivity of the signal implies the potential of the material for dating and retrospective radiation dosimetry.
