摘要：
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.
