Abstract

Carbon-doped Al₂O₃ is used as a material for dosimeter using thermoluminescence (TL) technique or optically stimulated luminescence (OSL) technique, and the emission bands are originated from defect emission. We have an original crystal growth named micro-pulling down (μ-PD) method which had higher temperature graduation during the crystal growth. Thus, crystal defect is easy to be formed without some dopant using the μ-PD method. We grew pure Al₂O₃ samples with different heating condition, and different peaks in TL spectra were obtained among the pure Al₂O₃.
