| 摘 要： | 用水热合成方法制备了PVP表面修饰CdS纳米棒，用XRD，TEM，TG-DTA，IR，UV-Vis，PL等光谱技术进行了表征。与未修饰的CdS纳米棒相比，PVP修饰后的CdS纳米棒具有更均匀的尺寸分布，吸收光谱具有结构峰特征，其荧光发射谱增强。

| Abstract: | Polyvinylpyrrolidone (PVP)-modified CdS nanorods were prepared by a hydrothermal reaction of CdCl2 2.5H2O and (NH4)2S with 10 wt% ethylenediamine aqueous solution as solvent and 1.0 wt% PVP as additives. The obtained products were characterized by means of XRD, TEM, IR, DTA-TG, UV-Vis and PL spectroscopies. The surface-modified CdS nanorods showed narrow size distribution and enhanced luminescence property compared with that of the unmodified ones. The UV-Vis spectra exhibited a structure peak. These results were attributed to the surface passivation of the CdS nanorods by the PVP molecules. |
