银纳米颗粒对四苯基卟啉Q带荧光寿命的延长
Extended Q-band fluorescence lifetime of tetraphenyl porphyrins adsorbed on silver nanoparticles
摘要
Abstract
The change of Q-band fluorescence lifetime of tetraphenyl porphyrins（TPP） adsorbed on the surface of silver nanoparticles is reported.The lifetime is extended when the surface plasmon resonant peak of silver nanoparticles is adjusted to be resonant with the Q- absorption band,which is due to the fact that silver nanoparticles bring a large surface plasmon resonant enhancement effect to the surface light field,and the excited TPP molecules have a higher polarity.The enhanced light field will stabilize the TPP molecules of high polarity,which causes the extended Q-band fluorescence lifetime.It has an important significance in photodynamic therapy using porphyrins as photosensitizer.关键词
