<p>A preparation method of zinc manganese silicate is provided. The method includes the following steps: step 1, preparing silicon dioxide sol with distilled water, anhydrous ethanol and tetraethyl orthosilicate; step 2, preparing a mixture solution of a zinc salt and a manganese salt; step 3, adjusting the silicon dioxide sol to be neutral or acidic; step 4, adding the mixture solution of the zinc salt and the manganese salt into the silicon dioxide sol to form a gelatin; step 5, drying the gelatin, keeping the temperature, grinding, reducing with keeping the temperature in a reductive atmosphere to obtain zinc manganese silicate. The preparation method has simple technique and low equipment requirement. The particles of the zinc manganese silicate phosphor prepared by the method have a regular size, uniform shape and good luminescent performance.</p> |
