摘要: 本文报道用四硫富瓦烯四硫醇盐(TTFS44-,简写TTFS4)修饰CdS、NiS的纳米微粒的方法,通过TEM、FT-IR等手段对修饰的纳米微粒进行了表征。实验发现CdS/TTFS4的固体荧光强度随着修饰量的增加而逐渐减弱。表面修饰后的CdS和NiS的电导率比修饰前都有提高,后者更为明显。 |

Abstract: CdS and NiS nanoparticles surface-capped with tetrathiafulvalene tetrathiolate (TTFS44-) have been synthe-sized. They were characterized by means of TEM and FT-IR etc. The fluorescent intensity of the solid samples CdS/TTFS4 decreased when the modified quantity increased. The conductivity of these surface-modified sulfides was higher than that of the pure sulfide, especially for NiS/TTFS4. |
