| 英文摘要 | The three composites Y2O3:Er3+, Y2O3:Er3+/Yb3+ and Y2O3:Er3+/TiO2 were prepared using coprecipitation and sol-gel techniques. Their morphology, specific surface area, porosity, UV-vis. absorption spectra and fluorescence spectra were measured using SEM, TEM, surface analysis, UV-vis. absorption and photoluminescence spectrophotometry. SEM and TEM showed that samples prepared using coprecipitation were dispersed, while Y2O3:Er3+/TiO2 particles possessed a mesoporous surface and average diameter of about 10 nm. The specific surface area and porosity of Y2O3:Er3+/TiO2 did not result from the combination of the individual properties of Y2O3:Er3+ and TiO2. The specific surface area of Y2O3:Er3+/TiO2 was 135.991 m(2)/g and was 4.8 times that of Y2O3:Er3+ and 2.5 times that of Degussa P25 TiO2. A high specific surface area is conducive for application to TiO2 photocatalysis. The fluorescence spectra of the three composites exhibited three upconversion emission peaks with maxima at 237, 395 and 467 nm following excitation at 388, 500 and 570 nm, respectively. |
