摘要
Al2O3 Single crystals were grown by the laser heated pedestal growth (LHPG) technique for potential use in radiation dosimetry using optically stimulated luminescence. The crystals were grown in the form of short single crystal fibers under a variety of growth conditions. Thermoluminescence (TL), radioluminescence (RL), cathodoluminescence, photoluminescence and optically stimulated luminescence (OSL) measurements were carried out on all fibers to assess their potential in luminescence radiation dosimetry. Measurements of luminescence spectra and the TL and OSL dose response characteristics lead to the suggestion that LHPG fibers have attractive luminescence dosimetry properties and warrant further study for potential applications in radiotherapy using OSL.
