| 英文摘要 | A new method is reported for the preparation of zn1-xmgxo semiconductor nanoparticles on subinicrosized sio2 by the transfer of the zn(ac)center dot 2h(2)o and mg(ac)(2)(.)4h(2)o ethanol mixed solution phase to monodisperse sio2 core substrate and further 800 degrees c thermal treatment. the zn1-xmgxo shell sizes on monodispersed sio2 core were estimated to be 17 nm by xrd, tem and sem. edx showed the presence of zn, mg, o, and si elements. uv-vis spectra indicated that sio2/zn1-xmgxo sample had a slight blue shift of the band gap and a higher uv absorption value than sio2/zno sample. infrared spectroscopy illustrated the formation of interfacial bond between sio2 and zn1-xmgo, that replaced surface silanol groups of sio2 the photoluminescence spectrum of sio2/ zn1-xmgxo sample excited at 290 mn showed a strong ultraviolet emission at 398 nm, and two strong blue luminescence peaks centered at about 451 nm and 468 nm. |
