Temperature dependence of the luminescence decay in the fluorescent dyes

Abstract


      The main aim of this study was to use laser induced fluorescence (LIF) technique to study and compare the temperature dependence of the luminescence decay curves of the fluorescent dyes; such as green dye, orange dye, and red dye. The 470 nm blue laser was used as an excitation light source to induce fluorescence. The LIF spectra were detected by a compact fiber coupled BTC-110S CCD spectrometer. All the controls and data acquisition were performed under a computer interfacing software. It was found from the experiment that the fluorescence spectra off fluorescence dyes possess temperature dependent properties, for both peak intensity and spectrum peak-value. The fluorescent intensity decreases at higher temperature for all the samples under the investigation for the range of 25–55 oC and the orange dye was found to be the most temperature sensitive for this temperature range.
