1. method for preparing the zinc-aluminium silicate glass that zinc oxide nanocrystalline and rare earth ion mix altogether may further comprise the steps:

  • 1) Zinc oxide powder, silicon-dioxide, aluminum oxide, potassium oxide and rare earth oxide are put into mortar, pour into after mixing in the crucible, the mass ratio of Zinc oxide powder, silicon-dioxide, aluminum oxide, potassium oxide and rare earth oxide is 35 ~ 43;

    25 ~ 36;

    15.2;

    14;

    0.2;

    2) crucible of step

         1) is put into High Temperature Furnaces Heating Apparatus, be warming up to 1560 ℃

    , be incubated 2 h fusions with 7~

    10 ℃

    /min temperature rise rate;

    3) with step

         2) fused solution be poured on 300~

    500 ℃

    copper coin or the graphite cake and be cooled to room temperature, at 600~
