| 摘 要： | 以PVP为表面修饰剂,用微波合成法制备了粒径分布均匀性能稳定的洛美沙星-铽(LELX-Tb3 )纳米粒子,用扫描电镜、红外光谱和荧光光谱进行了表征.重点分析了PVP的引入对洛美沙星-铽纳米粒子的粒径分布、粒子形貌、红外光谱和荧光光谱的影响,发现PVP修饰后的洛美沙星-铽纳米粒子具有更均匀的尺寸分布,荧光发射峰强度增强;确证了PVP的用量是制备洛美沙星-铽纳米粒子的一个重要因素;探讨了PVP对LFLX-Tb3 荧光的增敏机理. |

| Abstract: | Polyvinylpyrrolidone(PVP)-modified LFLX-Tb3 nanoparticles were prepared by microwave radiation method.The obtained products were characterized by means of SEM,FTIR and fluorescence spectra.The surface-modified LFLX-Tb3 nanoparticles showed a narrow size distribution and enhanced luminescence property compared with that of the unmodified ones.These results were attibuted to the surface passivation of the LFLX-Tb3 nanoparticles by the PVP molecules.It is confirmed that the addition dosage of PVP is an important factor in the preparation of the LFLX-Tb3 nanoparticles.The reasons for luminescence enhancement were discussed. |
| Keywords: | Microwave irradiation PVP/LFLX-Tb~(3 )LFLX-Tb~(3 ) Nanoparticles Adsorption Fluorescence Charge transfer |
