초록

Eu와 Fe를 불순물로 첨가한 BGO 섬광체 단결정을 Czochralski 방법으로 육성하였다. 그리고 육성된 BGO 단결정의 trap 특성을 알기 위하여 활성화 에너지, 주파수인자 및 열발광차수 등 포획매개변수를 구하고, 이것을 순수 BGO 섬광체 단결정의 열형광 특성과 비교하였다. 그리고 육성된 BGO 단결정의 광투과율을 측정하였다.

Eu or Fe doped BGO scintillation crystals were grown by Czochralski method. In order to get information about traps in the grown BGO crystals, we measured trap parameters including activation energy, frequency factor and the kinetic order of thermoluminescence, and compared such parameters with thermoluminescent characteristics of pure BGO scintillation crystals. In addition, optical transmittance of the grown BGO crystals was measured.
