| 摘 要： | 通过多步骤的化学法合成了Gd2O3：Yb3+，Nd3+，Tm3+/SiO2/Ag纳米复合材料。利用XRD，TEM，EDS，XPS，CLSM等方法对样品进行表征。实验结果表明，具有低声子能、稳定的化学性质的Gd2O3作为上转换发光的基质，当掺杂的敏化剂Nd3+离子浓度为1.0%（n/n），激活剂离子Tm3+浓度为0.5%（n/n）时，上转换发光强度达到最大值。此外，表面吸附的Ag纳米颗粒，由于表面等离激元共振耦合作用，使得上转换发光蓝光波段的强度增强1.70倍。

| Abstract: | The Gd2O3:Yb3+,Nd3+,Tm3+/SiO2/Ag nanocomposite was synthesized by multi-step chemical methods. XRD, TEM, EDS, XPS and CLSM were used to characterize the prepared samples. The results indicate that the upconversion intensity reach to maximum when the doping concentration of Nd3+ and Tm3+ ions reach to 1.0% and 0.5% (n/n) in Gd2O3 matrix with low phonon energy and good chemistry stability, respectively. Moreover, the blue region intensity is enhanced 1.70 times obviously due to the surface plasmon resonance effect by absorbed Ag nanoparticles. |
