摘要：

A novel rare earth luminescent material La2O2CO3 was synthesized successfully by sintering the mixture of La-2(CO3)(3) and KCl powders. The XRD results revealed that the additive KCl not only affected the crystal form and crystallinity of the final product, but also greatly promoted its luminescence, compared with the products without adding KCl. The as-prepared material showed a strong green emission band centered at 470 nm under the excitation of 325 nm. Our experimental results indicated that the crystal form of La2O2CO3 affected its luminescent properties significantly. According to the primary analysis, the green emission might be related to the oxygen vacancies in La2O2CO3 lattice.
