研究了含Ba(2)LaF(7)纳米晶的Er(3+)掺杂微晶玻璃的制备工艺及上转换发光性能。通过X射线衍射证实了玻璃陶瓷中Ba(2)LaF(7)纳米晶体的形成。与玻璃相比，含有Ba(2)LaF(7)纳米晶的Er(3+)掺杂玻璃陶瓷表现出高效的上转换发光。随着热处理温度的升高，上转换发光强度逐渐增强。还发现玻璃的成分对玻璃陶瓷的结晶过程有显着影响。通过控制玻璃的不同组成，可以获得Ba(2)LaF(7)和La(2)O(3)纳米晶的混合物以及La(2)F(3)和La(2)O(3)纳米晶的混合物。玻璃陶瓷中不同纳米晶体的上转换发光强度也有显着差异。
The preparation process and upconversion luminescence of the Er(3+)-doped glass ceramics containing Ba(2)LaF(7) nanocrystals were investigated. The formation of Ba(2)LaF(7) nanocrystals in the glass ceramics was confirmed by X-ray diffraction. Er(3+)-doped glass ceramics containing Ba(2)LaF(7) nanocrystals exhibited highly efficient upconversion luminescence in comparison with glasses. With the increase of heat treatment temperature the upconversion luminescence intensity increased gradually. The composition of glasses was also found to have significant influence on the crystallization process of glass ceramics. The mixture of Ba(2)LaF(7) and La(2)O(3) nanocrystals and the mixture of La(2)F(3) and La(2)O(3) nanocrystals in the glass ceramics could be obtained by controlling different compositions of glasses. The upconversion luminescence intensity also varied significantly with different nanocrystals in the glass ceramics.
