GREEN LUMINESCENT MATERIAL OF TERBIUIM DOPED GADOLINIUM BORATE AND PREPARING METHOD THEREOF |
摘要 |
<p>A green luminescent material of terbium doped gadolinium borate is provided. The luminescent material has a formula of M3Gd1-xTbx(BO3)3, 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 (BO3 3-), Gd3+ and Tb3+ by the stoichiometric ratio, wherein, the stoichiometric ratio is the molar ratio of the corresponding element in the formula of M3Gd1-xTbx(BO3)3, and the source compound of BO3 3- isover 10%-30% by the molar ratio; mixing; pre-treatment by sintering; cooling; grinding; calcination; and cooling to obtain the luminescent material.</p> |
