| Abstract: | The matrix Al 18 B 4O 33 is prepared by solid state reaction method in Al 2O 3-B 2O 3 system. Samples of the matrix obtained at different firing temperature and time are analyzed by X-Ray Diffraction, the result of which shows that Al 18 B 4O 33 can be obtained at about 1?100 centigrade.In addition Al 18 B 4O 33 :Eu 3+ phosphors are prepared by solid state reaction method for the first time.Through an analysis on microstructure of matrix and phosphors are studied by Scanning Electronic Microscopy, fluorescence spectra of Al 18 B 4O 33 :Eu 3+ are measured.The findingss show that the strongest fluorescence peak of phosphors is at 618.2nm,and phosphors emission light is at 591.86nm,613.39nm,698.11nm,703nm.which indicates that Al 18 B 4O 33 :Eu 3+ is a red emitting phosphors with high emission intensity,and itsThe emission mechanism is analyzed preliminarily In this paper. |
