以硫脲为硫源，在液相中以金属铕为原料合成了粒径可控的硫化铕纳米粒子。NH3，通过FT-IR测量证实其表面用硫脲修饰，并通过使用含有EuS纳米颗粒的PMMA膜研究了其光磁性质（法拉第效应），表明其法拉第旋转峰可通过控制其颗粒尺寸来调节。
Size-controlled EuS nanoparticles were synthesized by the reaction of europium metal with thiourea as a sulfur source in liq. NH3, whose surface was confirmed to be modified with thiourea by FT-IR measurement, and the opto-magnetic properties (Faraday effect) of the EuS nanoparticles were investigated by using PMMA films containing the nanoparticles, showing that their Faraday rotation peaks were adjustable by control of their particle size.
