Özet
Eu3+-doped Mg3-xEux(BO3)(2) (x=0.000, 0.005, 0.010, 0.020, 0.050, and 0.100) phosphors were synthesized for the first time by solution combustion synthesis method, which is a fast synthesis method for obtaining nano-sized borate powders. The optimization of the synthesis conditions of phosphor materials was performed by TG/DTA method. These phosphors were characterized by XRD, FTIR, SEM-EDX, and photoluminescence, PL analysis. The XRD analysis exhibited that all of the prepared ceramic compounds have been crystallized in orthorhombic structure with space group Pnnm. Also, the influence of europium dopant ions on unit cell parameters of host material was analyzed using Jana2006 program and the crystalline size was determined by Debye-Scherrer's formula. The luminescence properties of all Eu3+-doped samples were investigated by excitation and emission spectra. The excitation spectra of Mg3-xEux(BO3)(2) phosphors show characteristic peak at 420nm in addition to other characteristic peaks of Eu3+ under emission at 613nm. The emission spectra of Eu3+-doped samples indicated most intensive red emission band dominated at 630nm belonging to (D0F2)-D-5-F-7 magnetic dipole transition. Furthermore, the optimum or quenching concentration of Eu3+ ion has been determined as x=0.010 showed the maximum emission intensity when it was excited at 394nm.
