Abstract
A green luminescent material of terbium doped gadolinium borate is provided. The luminescent material has a formula of MGdTb(BO), wherein, M is alkaline earth metal element and x is 0.005-0.5. The method for preparing the luminescent material comprises the following steps: selecting the source compounds of alkaline earth metal ion, boric acid radical ion (BO), Gdand Tbby the stoichiometric ratio, wherein, the stoichiometric ratio is the molar ratio of the corresponding element in the formula of MGdTb(BO), and the source compound of BOis over 10%-30% by the molar ratio; mixing; pre-treatment by sintering; cooling; grinding; calcination; and cooling to obtain the luminescent material.
