| titleOfInvention | White ultra-long afterglow luminescent material and preparation method thereof |
| abstract | The invention belongs to the field of the materials and in particular relates to a near ultraviolet and visible light excited white ultra-long afterglow luminescent material and a preparation method thereof. The general formula of the luminescent material is (M, M*O)1-x-y.(EuO)x.(MnO)y.aAl2O3.bSiO2(1). In the formula, M and M* are one or more metallic elements selected from magnesium, calcium, strontium, barium and zinc, and a, b, x and y are amount of substance and respectively meet the following formulas: 0.5<=(a+b)<=5, b=(0.1-10)a, 0.001<=x<=0.1 and 0.001<=y<=0.5. The luminescent material is a white luminescent light storing body activated by co-doping europium and manganese or co-doping europium, manganese and one or more other rare earth (RE) elements or subjecting the elements to energy transfer with other ions. The luminescent material has the beneficial effects that the sintering body has a loose structure and is easy to break; the powder grain size is about 2-5 microns; the luminescent material has good weather resistance and acid and alkali corrosion resistance and white afterglow; and the afterglow time exceeds 12 hours. |
