초록 | If rare earth ions could be activated by electrical means after introducing into an appropriate semiconductor host, it might be possible to achieve the electrically-driven optical amplifier. Futhermore, some groups report that rare earth doped semiconductor nanoparticls show the sensitized emission. In this study, we try to prepare the Er/PbS nanoparticles encaupsulated by phenyl modified silica shell via sol-gel process. Er/PbS nanoparticles were characterized by UV-Vis absorption, XRD, FT-IR and TEM etc. Finally we will present the luminescence properties of Er doped PbS nanoencapsulation. 참고문헌 [1] B.Capoen, A.Martucci, S.Turrell, M.Bouazaoui, Applied Journal of Molecular Structure, 651-653 (2003) 467-473 [2] N.N.Parvathy, G.M.Pajonk, A.Venkateswara Rao, Applied Journal of Crystal Growth, 179 (1997) 249-257 |
