dc.description.abstract | Y3Al3B2O12 polycrystalline singly doped and co-doped with RE3+ ions (RE = Tb or/and Eu) have been synthesized by the solid-state interaction method at a temperature of 1250oC. The measurements of the luminescence excitation and luminescence spectra have been carried out at room temperature. The emission-color feature of materials was analyzed by CIE chromatic coordinates diagram and the correlated color temperature. The optimal concentration of RE3+ ions for emission of materials was found by studying the luminescence spectra. The rate and efficiency of the energy transfer process from Tb3+ to Eu3+ in Y3Al3B2O12:Tb3+,Eu3+ polycrystalline have also been calculated based on the lifetime of the 5D4 level of the Tb3+ ion. | vi |
