| In Summary, ɑ-NaYF4 and β-NaYF4 nanocrystals were precipitated in the transparent Zincatesilion oxyfluoride glass by adjust the relative content of glass components of ZnO and Na2O, respectively. With the increase of ZnO/Na2O ratio, the glass network connectivity was greatly enhance, which resulted in the increase of glass transition temperature and crystallization temperature. Under 980 nm excitation, the characteristic Tb3+ emissions were observed in NaYF4:Tb3+/Yb3+ glass ceramics. In comparison with the cubic sample, the hexagonal NaYF4 can emit enhanced UC luminescence. Moreover, under 393 nm excitation, the symmetry around Eu3+ in cubic NaYF4 glass ceramics is higher than that in hexagonal sample. |

第一，by adjust中的adjust要用动词ing形式，第二，建议用一般现在时，第三，increase那句，有两个increase，建议换个词，比如growth等 发自小木虫Android客户端 |

| In Summary, ɑ-NaYF4 and β-NaYF4 nanocrystals were precipitated within the transparent Zincatesilion oxyfluoride glass by adjusting the ratio of (relative content of) ZnO and Na2O of the glass components, respectively. As the ratio of ZnO/Na2O increased, the connectivity of the glass network was greatly enhanced, which resulted in increases of the transition and the crystallization temperature of the glass. Under excitation at 980 nm , the characteristic Tb3+ emission peaks were observed in NaYF4:Tb3+/Yb3+ glass ceramics. In comparison with the cubic sample, the hexagonal NaYF4 can emit enhanced UC luminescence. Moreover, under excitation at 393 nm , the symmetry (of the emission curve?) around Eu3+ in the cubic NaYF4 glass ceramics is higher than that in the hexagonal sample. |
