YAL(3)(BO3)(4):Eu3+ phosphors were fabricated by the sol-gel method. The structure properties were measured by x-ray diffraction (XRD) and infrared spectra (IR). Doping concentration of Eu3+ ions in YAL(3)(BO3)(4):EU3+ phosphors of 0, 1, 3, 4, and 5 mol% were studied. The excitation spectra and emission spectra of YAL(3)(BO3)(4):Eu3+ phosphors were examined by fluorescent divide spectroscopy (FDS). The luminescent properties of YAL(3)(BO3)(4):Eu3+ phosphors are discussion. The optimal doping concentration of EU3+ ions in YAL(3)(BO3)(4):Eu3+ phosphors was found to be approximately 3 mol%.
