中文摘要:

为可控制的荧光紧张的一个改进的班的制造的一个方法,高度敏感并且 photostable 卟啉做的硅石 nanoparticles (PDSNP ) 被表明。PDSNP 的荧光紧张能被细微地调节衔接卟啉的 silsesquioxane 的先锋的自我分裂的时间控制。卟啉很好在系统由于共有原子价附件被驱散进硅石矩阵,完全因此避免熄灭的卟啉漏和荧光完成。有一个狭窄的尺寸分布式的区域和常规球形的结构的结果的 PDSNP 能被达到。

英文摘要:

A method for the fabrication of an improved class of controllable fluorescence intensity, highly sensitive and photostable porphyrin doped silica nanoparticles (PDSNPs) was demonstrated. The fluorescence intensity of PDSNPs could be controlled by finely tuning self-dissociated time of the precursor of porphyrin-bridged silsesquioxane. Porphyrin was well dispersed into the silica matrix due to the covalent attachment in the system, thus entirely avoiding the porphyrin leakage and fluorescence quenching effects. The resultant PDSNPs with a narrow size-distributed region and a regular spherical structure can be attained.
