摘要	We successfully prepared Y2O3:Eu3+/C3N4 composite nanotubes by combining the hydrothermal with chemisorption method for the first time. The infrared spectra indicated that the C-N (1238 cm(-1)) stretching vibration peak moved to a higher wavenumber with increasing the amount of Y2O3:Eu3+, suggesting the formation of Y2O3:Eu3+/C3N4 composite nanotubes. The charge transfer bands showed a little blue-shift after compositing with C3N4 in the excitation spectra of Y2O3:Eu3+/C3N4 composite nanotubes monitored at 615 nm. More importantly, the sharp lines originate from Eu3+ f-f electron transitions almost vanished in the excitation spectra of Y2O3:Eu3+/C3N4 composite nanotubes, which was attributed to the interaction between C3N4 and Y2O3:Eu3+. The decay curve of Y2O3:Eu3+ and Y2O3:Eu3+/C3N4 composite nanotubes can be fitted with the biexponential function well. The luminescence lifetimes of Y2O3:Eu3+ increased by combining C3N4.
