摘要：

Highly efficient Ba3Si6O12N2 green-emitting phosphors using boron-coated Eu2O3 were synthesized by a gas reduction nitridation method under flowing NH3 gas. X-ray diffraction patterns showed that the synthesized phosphor was a pure phase of Ba3Si6O12N2. The Ba3Si6O12N2 green-emitting phosphors synthesized by modification of an alumina boat were crystallized much better as well as showed higher emission intensity. The emission spectra showed a typically broad green emission band attributed to the 4f(6)5d-->4f(7) electronic transition of Eu2+ ions under excitation at 405 nm. The green-emitting Ba3Si6O12N2 phosphors that were synthesized using boron-coated Eu2O3 by modification of an alumina boat could be applied to generate white light emitting diodes.
