| 摘 要： | 采用EuCl3对负载1,8-萘二酸酐（NA）的双模型介孔分子筛(BMMs)进行改性，以期提高此类杂化材料的荧光性能，并且利用XRD、TEM、N2 吸附-脱附、FT-IR、TG等分析手段对样品进行了结构表征，采用荧光光谱仪(PL) 考察了其发光行为。结果表明，EuCl3改性后的BMMs仍然保持了双模型介孔结构特征，而且EuCl3对荧光性能有显著影响，造成1,8-萘二酸酐的特征发射峰蓝移，且荧光强度明显提高。

| Abstract: | Europium chloride was employed to modify 1,8-naphthalic anhydride(NA) loaded on bimodal mesoporous silicas (BMMs), and hopefully to improve its luminescent performance. The structural features of the obtained hybrids nanomaterilas were characterized by means of XRD, TEM, N2 adsorption-desorption, FT-IR, TG techniques, and their luminescence properties were investigated with help of photoluminescence (PL) measurements. The results showed that the bimodal mesopores of BMMs could be preserved after functionalization via grafted Eu3+ modified NA molecules. Meanwhile, the influences of the addition amount of EuCl3 on the luminescence performances were remarkable, with both of slight blue-shiftness of emission peak and obvious enhancement of luminescent intensity. |
