We have developed a new scaling property of the conductivity spectra of fluoride glasses. This property predicts the existence of a universal ionic relaxation in these glasses. The relaxation process in fluoride glasses is observed to be independent of temperature as well as the nature and concentration of the ionic charge carriers.
