ABSTRACT:

The lyoluminescence (LL) emission spectra of luminol, fluroscein & rhodamine-B (R-B) dyes have been recorded at optimum concentration of the activators in aqueous ethylamine. An enhancement of three & seven fold incrases in LL intensity of luminal has been observed at 9 ?10-5 M concentration of fluoresce in & 8?5-5 M concentration of R-B respectively, in the binary solution of luminol & dyes. The LL emission spectra of luminol-dye mixture are recorded at the concentration of enhancement in LL intensity of luminol. These spectra in resolution, should foure mission bands. The first two bands of 430 & 470 nm corresponds to LL to luminol & the other two bands of longer wavelength emission corresponds to LL of dye molecule. The observed enhancement of LL intensity is explain with the help of a mechanism based on the reactions of colour centers with activities.
