1. the manufacture method of a plasm display device, the fluorophor that this plasma display unit has luminescent coating, the described luminescent coating of formation of the arc chamber of configuration a plurality of monochromes or polychrome and the configuration color corresponding with each arc chamber carries out luminous plasma display by ultraviolet ray exited, it is characterized in that:

  • at least one in the described luminescent coating has the green-emitting phosphor layer, and this green-emitting phosphor layer contains;

    will SiO be arranged because of surface coverage 2And electronegative crystal structure is Zn 2SiO 4;

    the fluorophor powder of Mn, make with 1100 ℃

    1300 ℃

    roastings, fluorophor after described roasting made slightly is crushed to the chip-proof degree of crystal plane and sieves, after utilizing ball mill or jet mill to be ground into 0.9 times~

    0.5 times of the particle diameter of particle diameter before the fluorophor after the screening for the crystal face fragmentation, in nitrogen, in nitrogen-oxygen, perhaps anneal and the green-emitting phosphor of positively charged with 400 ℃

    1000 ℃

    in nitrogen-water vapour, being situated between, to help nozzle will be that the green-emitting phosphor printing ink of main component is applied to described arc chamber with described green-emitting phosphor, form described green-emitting phosphor layer thus.
