[0025] The present invention also provides a preparation method of the luminescent material, which specifically includes the following steps:
[0026] (1) Weigh M according to molar parts 2 O, SiO 2 、H 3 BO 3 , CaF 2 、Re 2 o 3 , mixed and ground in a mortar evenly to obtain mixed raw materials;
[0027] (2) Calcining the mixed raw material prepared in the step (1) at 1450°C to 1650°C for 1 to 1.5 hours to form a molten material;
[0028] (3) Pour the molten material in the step (2) into the mold, use water mist to assist to cool down to 400-450°C within 15s, and then slowly cool to room temperature to obtain a solidified body;
[0029] (4) Annealing the cured body prepared in the step (3) at 450-550° C. to obtain the luminescent material.
