초록
2자리 리간드를 사용하여 BaWO4 결정을 합성하였다. 리간드의 농도와 [WO4 2.]/[Ba2+] 비율과 같은 반응 변수 는 다양한 형태의 BaWO4 결정을 형성하는데 매우 중요한 역할을 한다. TMEDA를 리간드로 사용했을 때는 250 nm의 폭과 2~3 μm의 길이를 가진 십자형의 단면들의 자기 조립에 의해서 15~20 μm 길이의 마이크로 막대형의 BaWO4 결정을얻었다.
Abstract
BaWO4 crystals were synthesized using bidentate ligands. The reaction parameters such as the concentration ofligand and molar ratio of [WO42]/[Ba2+] played important roles in the formation of BaWO4 crystals with various morphologies.When TMEDA was used as a ligand, the microrods of BaWO4 crystals with length of 15~20m were formed via the selfassembly of cross-like plates of 250 nm in width and 2~3m in length.Key words BaWO4, Bidentate ligand, Morphology2.. .... ...
