Fluorescence Spectra and Lifetimes of Several Fluorophores Immobilized on Nonionic Resins for Use in Fiber-Optic Sensors

摘要

Fluorescence emission spectra and lifetimes are reported for 0.01-1.0 nM samples of rhodamine B, rhodamine 6G, eosin Y, and fluorescein each adsorbed on XAD-2 and XAD-4 resins. Trends are discussed and comparisons made between bound fluorophore and fluorophore in solution. The systems appear to be useful in fiber-optic-based sensors.
