The role of Ga2O3 in the preparation of Y2O3:Eu3+ phosphor from the oxides

It has been observed that Ga2O3 enhances the cathodeluminescence and the 2537 Å-excited photoluminescence, and also causes whitening of the body colour of Y2O3:Eu2+ prepared from the oxides. In both types of luminescence, these effects are apparently due to the Ga2O3 behaving as a mineraliser, i.e. a diffusion enhancer. In the case of photoluminescence, additional brightness enhancement resulting from incorporation of Ga2O3 is due to a type of sensitisation to the exciting wavelength.
