Time-resolved optically stimulated luminescence from α-Al2O3:C

Time-resolved optically stimulated luminescence and spectral emission features of α-Al2O3:C

“…Kinetic analysis shows that the kinetic energy of peak I is equal to 0.72±0.05 eV [9] or similar [8,18], the least for all peaks in -Al 2 O 3 :C. We therefore conclude that the electron trap responsible for peak I is consistent with the C Al site. Further, different concentrations of C Al in the material could account for the existence of types A and B samples.…”

Recovery of α-Al2O3 from Ionizing Radiation Dosimetric Sensors

“…As reported by Markey, Colyott and Mckeever, 20 the grain size of the Al 2 O 3 :C powder is in the range of 10-90μm. As it was determined from Landauer's previous experience, excessive amounts of "fine" grains (less then 38μm) and "large" grains (>75μm) can create problems during printing.…”

Role of Ti4+ in the luminescence process of Al2O3:Si,Ti

“…The emission at 410-420 nm is also the main emission band observed in TL from Al 2 O 3 :C [16]. Markey et al [18] measured the time-resolved OSL emission spectrum from irradiated Al 2 O 3 :C following pulsed stimulation with 514 nm line from an Ar-ion laser. They demonstrated that emission peak near 410-420 nm remained fixed at this wavelength during the entire decay process.…”
