1. the preparation method of a metal nano particle-doped manganese-doped willemite luminescent material is characterized in that, comprises the steps:

  • Step 1 joins metal nanoparticle solution in the solution that is dissolved with polyvinylpyrrolidone;

    Step 2 is added dehydrated alcohol, deionized water and ammoniacal liquor successively in the described solution of step 1, stir, and then under agitation adds tetraethoxy, and the reaction back is separated dry, obtains being coated with the SiO of metal nanoparticle 2Powder;

    Step 3 according to stoichiometric ratio, takes by weighing the SiO that is coated with metal nanoparticle that makes in the compound of Zn and Mn correspondence and the step 2 2Powder, ground and mixed is even, obtains mixture powder;

    Step 4 is warming up to 1000 ℃



    1350 ℃

    calcinings 2~

    15 hours with mixture powder, is cooled to room temperature and makes metal nano particle-doped manganese-doped willemite luminescent material after 0.5~

    6 hour in reduction under this temperature and the reducing atmosphere again.
