Abstract
Ba3Si6O12N2 green-emitting phosphors were synthesized using oxide precursor by liquid phase precursor (LPP) method under a flowing NH3 gas. X-ray diffraction patterns showed that the prepared phosphor indicated a Ba3Si6O12N2 pure single phase. The emission spectra of synthesized phosphors under excited from UV to blue light showed a typically broad green emission wavelength which is assigned to 4f65d→4f7 electronic transition of Eu2+ ion. Compared with emission intensity of prepared sample, the emission intensity of Ba3Si6O12N2 green-emitting phosphors using LPP method is more than 2.5 times than that of Ba3Si6O12N2 green-emitting one by a solid state reaction method. The synthesis of phosphor using the LPP method is expected as alternative synthesis method.
