Team 3: GVSU Department of Chemistry - Project: Fluorescent Decay Measurement Device

Project Abstract

The fluorescence decay time of a material provides insight into a material’s physical-chemical properties. This project design will allow for the accurate measurement of fluorescence decay time of an aqueous solution of [Ru(bpy)3]2+at varying concentrations. This will be accomplished by placing a [Ru(bpy)3]2+solution in a standard cuvette. The electrons of the[Ru(bpy)3]2+ ions will then be excited by a light pulse producing photons with a wavelength of 450nm. A 650nm optical filter and an avalanche photodiode (APD) will then be used to filter and collect the fluorescing photons. The current out of the ADP will be converted into a voltage waveform using a trans-impedance amplifier. A second stage voltage amplifier will be used to output a voltage waveform with an amplitude large enough to be measured on an oscilloscope.
