초록

Micro-pulling down법을 이용하여 $Nd_2O_3$가 첨가된 crack 등의 결함이 없는 화학양론조성의 $LiNbO_3$ 단결정을 직경 1 mm, 길이 30∼35 mm의 크기로 성장시켰다. Electron probe micro analysis를 이용하여 결정 내에 $Nd_2O_3$가 균일하게 분포되어있음을 확인하였다. 성장된 결정의 $Nd_2O_3$ 첨가에 따른 흡수 band를 관찰하였고 $Nd_2O_3$ 첨가량 변화에 따른 형광특성의 변화를 측정하였다.

Using the micro-pulling down method, $Nd_2O_3$ doped crack-free stoichiometric $LiNbO_3$ single crystals were grown in 1 mm diameter and 30∼35 mm length. The homogeneous distributions of $Nd_2O_3$ concentration were confirmed by the electron probe micro analysis. The absorption and photoluminescence spectra were measured with respect to the $Nd_2O_3$ doping.
