摘要：

A novel complex fluorescent probe based on quantum dots and organic dye (QDS TO) was designed and prepared by incorporating a benzothiazole derivative into QDs-1-(3-amidepiopyl)-4-methylquinoline The complex probe was characterized by FT-IR and TG/DTA The emission wavelength of QDs-1-(3-amidepropyl)-4-methylquinoline was found at 475 nm rind a new peak corresponding to QDs-TO appeared at 550 nm indicating that benzothiazole derivative can react with QDs 1-(3-amidepropyl)-4-methylquinoline to afford QDs-TO Furthermore the emission wavelength of QDs shifted blue while the characteristic peak of TO shifted red during the reaction Thl, suggests that the probe may be useful for biological labeling in offering an efficient method to study the interrelation between quantum dots and organic dyes (C) 2010 Elsevier BV All rights reserved
