✦ Synopsis

Phosphor particles are often coated with thin layers of inorganic materials in order to improve various screening factors. As part of a general study on the effect of coatings on the cathodoluminescence of phosphors, the effect of high-density cathode-ray excitation has been investigated [ 11 . Such studies indicated that there is a luminescence degradation, which is thermal in nature, as a function of time. By plotting this luminescence thermal degradation as a function of coating concentration, obtained by independent analytical means, a method of quantitative analysis was evolved, valid for a particular coating on a particular host phosphor.

One approach to measuring temperature in oxide coatings is to incorporate, within the crystal structure of the coating material itself, ions ("chromophores") with temperature-dependent luminescence properties. The attraction of this "crystal chemistry" approach is that the other properties of the co
