It was found that sodium hexametaphosphate (SP), as an enhancer, could increase the chemiluminescence (CL) emission from the redox reaction of CdTe quantum dots with potassium permanganate in near\u2010neutral pH conditions. <jats:sc>l<\/jats:sc>\u2010Ascorbic acid is suggested as a sensitive enhancer for use in the above energy\u2010transfer excitation process. Under optimal conditions, the calibration graph of emission intensity against logarithmic <jats:sc>l<\/jats:sc>\u2010ascorbic acid concentration was linear in the range 1.0\u2009\u00d7\u200910<jats:sup>\u22129<\/jats:sup>\u20135.0\u2009\u00d7\u200910<jats:sup>\u22126<\/jats:sup>\u2009mol\/L, with a correlation coefficient of 0.9969 and relative standard deviation (RSD) of 2.3% (<jats:italic>n\u2009=<\/jats:italic>\u20097) at 5.0\u2009\u00d7\u200910<jats:sup>\u22127<\/jats:sup>\u2009mol\/L.
