Provided are a borosilicate luminescent material and a preparing method for making the material. The borosilicate luminescent material has a chemical formula of aM 2 O·bLn 2 O 3 ·cAl 2 O 3 ·dR 2 O 3 ·eSiO 2 ·fCeO 2 ·gTb 2 O 3 , wherein, M is alkaline earth metal or alkali metal, Ln is one or two elements selected from the group consisting of yttrium and gadolinium, R is one or two elements selected from the group consisting of boron and phosphorus, the a, b, c, d, e, f, and g are molar fractions, and 6‰¤a‰¤20, 3‰¤b‰¤12, 20‰¤c‰¤30, 32‰¤d‰¤45, 0‰¤e‰¤12, 0.01‰¤f‰¤1, and 0.05‰¤g‰¤1.5. The preparing methods comprises the following steps: 1 ) providing the compounds used as the sources of the above elements; 2 ) mixing and grinding the compounds to get a mixture; 3 ) pre-sintering the mixture and then grinding the mixture to get a pre-sintered matter; 4 ) sintering the pre-sintered matter in reducing atmosphere and then cooling the sintered matter to get the borosilicate luminescent material. |
