Abstract

doped borosilicate glass has been prepared. The as-made glass was heat-treated and crystallized. X-ray diffraction (XRD)

TEM

absorption spectrum and emission spectrum of glass ceramics were measured. Crystallite size of BaYF

glass ceramics were calculated by Scherrer formula and the comparing with the result of TEM. White emission band (300~800 nm) originated from the charge transferring of Ti

(3d

)-O

) can be observed in Ti

doped borosilicate glass ceramics. Comparing with the as-made glass

significantly increased luminescence was observed in the glass ceramics. By optimizing the heat treat temperature and concentration of Ti

borosilicate glass ceramics with CIE coordinate (0.261

0.351) can be obtained which is close to the standard white-light illumination (0.333

0.333).
