abstract = "The Pr3+/Tb3+-BaLaGa3O7 color-controllable phosphors were synthesized by a facile high-temperature solidstate reaction technique. The X-ray diffraction patterns, the photoluminescence excitation (PLE) spectra and photoluminescence (PL) spectra
were measured to characterize the prepared phosphors. Under the 280 nm excitation, the characteristic emissions of Pr3+,Tb3+ and Pr3+/Tb3 ions were observed. Moreover, the emission color of the BaLaGa3O7: Pr3+,Tb3+
phosphors was tuned to white by adjusting the Tb3+ ion concentration. The PL spectra revealed that there is an efficient energy transfer (ET) from Tb3+ to Pr3+ ions and the ET efficiency was found to be as high as 61.9%. These obtained white light-emitting
BaLaGa3O7: Pr3+,Tb3+ phosphors were expected to be a potential candidate for phosphor converted white light-emitting diode applications.",
