Abstract
Photoinduced electron transfers between Nile red (NR) with TiO2 colloidal nanoparticles are studied using picosecond transient absorption and time resolved fluorescence spectroscopy. The dynamics of electron transfer from the dye molecule to the semiconductor were understood from the transient, and also the formation of conduction band electron and Nile red cation radical were detected.
摘要
利用皮秒瞬态吸收光谱和时间分辨荧光光谱研究了尼罗红（NR）与二氧化钛胶体纳米颗粒之间的光致电子转移。从瞬态过程中了解了染料分子向半导体的电子转移动力学，并且检测到了导带电子和尼罗红阳离子自由基的形成。
