| Abstract: | In this paper,light-emitting diode(LED) source as excitation light pulses is used to study the transient spectra characteristics of rhodamine B.Excitation light source with three central wavelengths are 406 nm,464 nm and 528 nm super bright purple,blue and green LED.Experimental results show that the fluorescence intensities are very different with the different excitation light color(wavelength),pulse duration and different concentration of the rhodamine B.In the same concentration,if the excitation durati... |
