ABSTRACT
The SrAl2B2O71%Eu3+ phosphors were obtained by solid-state reaction. Photoluminescence (PL) spectra are characterized the property of samples, and under the excitation of 394 nm, the sharp emission lines of SrAl2B2O71%Eu3+ can be assigned to Judd-Ofelt transitions (5D0-7FJ) of Eu3+, which are 5D0-7F1, 5D0-7F2, 5D0-7F3, and 5D0-7F4. The bond energy method is used to determine the site occupancy, and the occupancy of Eu3+ can be determined by comparing the deviation of its bond energy in different locations at Sr2+, Al3+ and B3+ sites. Theoretical calculation result indicates that Eu3+ would preferentially occupy the smaller energy variation sites Sr2+.
