摘要：

Y2O3:Eu3+ thin films were grown on quartz fabric substrate by electron beam evaporation (EBE) at different deposition temperatures. It was found that an increase of deposition temperature from room temperature (R.T.) to 250 degrees C results in improved morphologies of the films, such as reduced defects, spherical particle shape and dense surface topography. A change in the predominant orientation of Y2O3:Eu3+ thin films was detected from (222) at low temperatures of R.T.-150 degrees C to (400) at higher temperatures of 200-250 degrees C. The luminescent intensity of the films was gradually improved with an increase in deposition temperature and the optimal brightness was observed when the films were grown at 250 degrees C and improved by 32.67% in comparison with that of the films grown at R.T. The results reveal that the improved morphologies and effective crystallization can contribute to the enhanced luminescent properties of the Y2O3:Eu3+ thin films.
