We demonstrate that electorogenerated chemiluminescence (ECL) of an organometallic Eu(III) complex, tris(dibenzoylmethane)phenanthroline europium(III), whose emission spectra is very sharp with the maximum wavelength of 612 nm, can be used as a light source for the detection of PO4 3based on changing the absorbance of the ion associate of malachite green (MG + ) and phosphomolybdic acid. The ECL was also applied to measure the absorbance of MG + . With the detection system we established,
