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 (XRD), Fourier Transform Infrared Microscopy (FTIR), Simultaneous Thermal Analysis STA (Thermo Gravimetric Analysis (TGA)/Differential Scanning Calorimetry (DSC)) and Scanning Electronic Microscopy (SEM) techniques. XRD and STA analysis suggested an enhancement in crystallinity and thermal stability of the BeO with increasing sintering temperature.

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.
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...
Infrared (IR) stimulated luminescence from feldspars with linearly increasing excitation light intensity Bulur, Enver (1999-01-01) IR stimulated luminescence signal from potassium and sodium feldspars were studied by linearly increasing the excitation power from zero to a maximum value during the readout. The peak shaped signals observed in both feldspars could be approximated using a linear combination of three first-order components as deduced by curve fitting. The thermal and radiation dose dependent behavior of the IR-stimulated OSL curves were also studied. (C) 1999 Elsevier Science Ltd. All rights reserved.
Time-resolved OSL studies of YAlO3:Mn2+ crystals Zhydachevskii, Ya.; LUCHECHKO, A; MARABA, DİREN; MARTYNYUK, N; GLOWACKİ, M; Bulur, Enver; UBİZSKİİ, S; BERKOWSKİ, M; SUCHOCKİ, A (2016-11-01) 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+ p...
Phototransferred thermoluminescence from α-Al2O3:C using blue light emitting diodes Bulur, Enver (1999-01-01) Phototransferred thermoluminescence (PTTL) from alpha-Al2O3:C single crystals was studied using a blue light emitting diode (LED) for phototransfer of charges from deep traps to the main dosimetry trap. The dose response was found to be linear in the region from similar to 5 mGy to similar to 5 Gy. It was observed that the corresponding deep traps were located near 500 degrees C and heating to temperatures > 600 degrees C removes the PTTL effect induced by the light from the blue LED. The thermal activation...
