Synthesis and luminescent property of Eu3+-doped LaSi3N5 phosphor

摘要: Abstract By a solid state reaction of LaN, Eu 2 O 3 and Si N 4 , LaSi 5 La 0.9 0.1 5− X LaEuSi were prepared at 1900°C for 2h under 1.01×10 6  N m −2 nitrogen pressure. These compounds identified by X-ray diffraction analysis, then characterized means absorption luminescence spectroscopies. was isostructural with . For only we observed broad emission band maximum 549 nm due to the 4f 5d→4f 7 transition 2+ On other hand, ion in showed deep-red 650 nm.
